The number is 80
To be a multiple of 4, 10 and 20 the number must be a multiple of their lowest common multiple. lcm(4, 10, 20) = 20 What is required is a multiple of 20 between 61 and 107. The numbers 80 and 100 both satisfy the problem of being between 61 and 107 and being a multiple of 4, 10 and 20.
The number is 90.
90
It is: 80
98
Only if they're the same number. The LCM and GCF of 10 and 10 is 10.
Only if you're comparing the number to itself. The LCM and GCF of 10 and 10 is 10.
80 and 100
When you are comparing a number to itself. The GCF and LCM of 10 and 10 is 10.
The LCM will be a multiple of 10, since 10 is the largest number given in the problem. The LCM is 60.
You need to have at least 2 numbers to have an LCM, otherwise the LCM will be the number you have. Ex. LCM of 10 = 10 LCM of 23786 = 23786 Lcm of 8 = 8 See? It's easy!
