Given numbers are 623, 518, 947, 556

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

Apply this formula for all numbers.

Step1:

LCM(623, 518) = 46102

GCD(623, 518) = ( 623 x 518 ) / 46102

= 623 / 518

= 623

Step2:

LCM(7, 947) = 6629

GCD(7, 947) = ( 7 x 947 ) / 6629

= 7 / 947

= 7

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 623, 518, 947, 556 is 1
