Given numbers are 96, 20, 21, 70
The list of prime factors of all numbers are
Prime factors of 96 are 2 x 2 x 2 x 2 x 2 x 3
Prime factors of 20 are 2 x 2 x 5
Prime factors of 21 are 3 x 7
Prime factors of 70 are 2 x 5 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 96, 20, 21, 70
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(96, 20) = 480
GCD(96, 20) = ( 96 x 20 ) / 480
= 96 / 20
= 96
Step2:
LCM(4, 21) = 84
GCD(4, 21) = ( 4 x 21 ) / 84
= 4 / 21
= 4
Step3:
LCM(1, 70) = 70
GCD(1, 70) = ( 1 x 70 ) / 70
= 1 / 70
= 1
So, Greatest Common Divisor of 96, 20, 21, 70 is 1
