Given numbers are 623, 840, 677, 557

The list of prime factors of all numbers are

Prime factors of 623 are 7 x 89

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 677 are 677

Prime factors of 557 are 557

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 623, 840, 677, 557

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(623, 840) = 74760

GCD(623, 840) = ( 623 x 840 ) / 74760

= 623 / 840

= 623

Step2:

LCM(7, 677) = 4739

GCD(7, 677) = ( 7 x 677 ) / 4739

= 7 / 677

= 7

Step3:

LCM(1, 557) = 557

GCD(1, 557) = ( 1 x 557 ) / 557

= 1 / 557

= 1

So, Greatest Common Divisor of 623, 840, 677, 557 is 1
