GCD of numbers is the greatest common divisor
So, the GCD (10, 64, 70, 45) = 1.
Given numbers are 10, 64, 70, 45
The list of prime factors of all numbers are
Prime factors of 10 are 2 x 5
Prime factors of 64 are 2 x 2 x 2 x 2 x 2 x 2
Prime factors of 70 are 2 x 5 x 7
Prime factors of 45 are 3 x 3 x 5
The above numbers do not have any common prime factor. So GCD is 1
Steps to Calculate GCD of 10, 64, 70, 45 using LCM Formula
Given numbers are 10, 64, 70, 45
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(10, 64) = 320
GCD(10, 64) = ( 10 x 64 ) / 320
= 10 / 64
= 10
Step2:
LCM(2, 70) = 70
GCD(2, 70) = ( 2 x 70 ) / 70
= 2 / 70
= 2
Step3:
LCM(2, 45) = 90
GCD(2, 45) = ( 2 x 45 ) / 90
= 2 / 45
= 2
So, Greatest Common Divisor of 10, 64, 70, 45 is 1
