Given numbers are 441, 646, 453, 631
The list of prime factors of all numbers are
Prime factors of 441 are 3 x 3 x 7 x 7
Prime factors of 646 are 2 x 17 x 19
Prime factors of 453 are 3 x 151
Prime factors of 631 are 631
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 441, 646, 453, 631
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(441, 646) = 284886
GCD(441, 646) = ( 441 x 646 ) / 284886
= 441 / 646
= 441
Step2:
LCM(1, 453) = 453
GCD(1, 453) = ( 1 x 453 ) / 453
= 1 / 453
= 1
Step3:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
So, Greatest Common Divisor of 441, 646, 453, 631 is 1
