Q: What is the LCM of 1 and 5?

Write your answer...

1 and 5 have an LCM of 5.

the LCM of 1,2 and 5 is ten.

The LCM is 60.

The LCM of 3, 5 and 7 is 105. The GCF is 1.

LCM(5, 1) = 5.

GCF=1. LCM=120

hcf is 1 and LCM is 35

The GCF is 1 and the LCM is 65.

It is LCM(2, 3, 4, 5, 6) + 1 = 60+1 = 61It is LCM(2, 3, 4, 5, 6) + 1 = 60+1 = 61It is LCM(2, 3, 4, 5, 6) + 1 = 60+1 = 61It is LCM(2, 3, 4, 5, 6) + 1 = 60+1 = 61

5

The only common factor between 5 and 9 is 1, so the LCM is simply 5 x 9 = 45.

The GCF is 1. The LCM is 60.

Since 5 and 9 have no common factors except 1, the LCM will be there product which is 45.

5(1) = 55(2) = 1010(1) = 10

75 because, 3,15,75 1,5,25(/3) 1,1,5(/5) Pf=3*5*1*1*5 lcm=15*5=75

1

10

The Least Common Multiple (LCM) for 6, 15, and 75 is 150...| 6 15 753 | 2 5 255 | 2 1 5lcm = 3 * 5 * 2 * 1 * 5 = 150

the lcm of 1 2 3 4 5 6 7 is 420

2 and 5 are coprime integers: they do not have any common factors. Therefore the GCF is 1 and the LCM is their product, 2x5=10.

45.(45 * 1)(5 * 9)

1

If there is no common factor greater than 1, then the lcm of those numbers is the product of those numbers. eg hcf(5, 7) = 1 → lcm(5, 7) = 5 x 7 = 35 eg hcf(4, 9) = 1 → lcm(4, 9) = 4 x 9 = 36

The LCM is 60. 5 = 5 x 1 2 = 2 x 1 3 = 3 x 1 4 = 2 x 2 Using the highest exponent of each prime, the LCM is 5 x 3 x 4 = 60

Find the LCM of 2,3,5 and 6 and add 1 which is the same as the LCM of 5 and 6 and add 1 which is the same as 31.
