Given numbers are 644, 470, 251, 736
The list of prime factors of all numbers are
Prime factors of 644 are 2 x 2 x 7 x 23
Prime factors of 470 are 2 x 5 x 47
Prime factors of 251 are 251
Prime factors of 736 are 2 x 2 x 2 x 2 x 2 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 644, 470, 251, 736
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 470) = 151340
GCD(644, 470) = ( 644 x 470 ) / 151340
= 644 / 470
= 644
Step2:
LCM(2, 251) = 502
GCD(2, 251) = ( 2 x 251 ) / 502
= 2 / 251
= 2
Step3:
LCM(1, 736) = 736
GCD(1, 736) = ( 1 x 736 ) / 736
= 1 / 736
= 1
So, Greatest Common Divisor of 644, 470, 251, 736 is 1
