Step-by-step explanation:
Greatest Common Factor
- first list all the numbers that could be multiplied to the factors given.
30 = 1, 2, 3, 5, 6, 10, 15, & 30
24 = 1, 2, 3, 4, 6, 8, 12 & 24
- then you find the common number between them but the highest one (which is 6)
Least Common Multiple
- so we could say this is the opposite of the greatest common factor
3 = 3, 6, 9, 12, 15, 18
4 = 4, 8, 12, 16, 20
- in here i listed the multiples of 4 & 3 and got the least common between them (which is 12)
Answer:
tbf i wouldnt get this if i read this for the first time
Step-by-step explanation:
write numbers down
draw a branch to split the number into a prime and the number it needs to multiply to get to it
e.g. 156 can split into
/ \
2 78
kee.p splitting the number.s
78 = 2, 39
39 = 3, 13
now do the same for the second number
e.g. 188
/ \
2 94
94 = 2, 47
draw a venn diagram
put the numbe.rs in the correct locatio.n
a repe.at number e.g. 2, 2, 2, 2 now wo.uld be two 2s because they essential.ly cancel each other out
156 188
13, 3 2, 2 47
for gcf you would times the number in the centre
2 x 2 = 4
4 is the gcf
for lcm you would times everything in the venn diagram
13 x 3 x 2 x 2 x 47 = 7332
7332 is lcm
