Given numbers are 100, 560, 595, 644
The list of prime factors of all numbers are
Prime factors of 100 are 2 x 2 x 5 x 5
Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7
Prime factors of 595 are 5 x 7 x 17
Prime factors of 644 are 2 x 2 x 7 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 100, 560, 595, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(100, 560) = 2800
GCD(100, 560) = ( 100 x 560 ) / 2800
= 100 / 560
= 100
Step2:
LCM(20, 595) = 2380
GCD(20, 595) = ( 20 x 595 ) / 2380
= 20 / 595
= 20
Step3:
LCM(5, 644) = 3220
GCD(5, 644) = ( 5 x 644 ) / 3220
= 5 / 644
= 5
So, Greatest Common Divisor of 100, 560, 595, 644 is 1
