Given numbers are 623, 616, 87, 438

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

Apply this formula for all numbers.

Step1:

LCM(623, 616) = 54824

GCD(623, 616) = ( 623 x 616 ) / 54824

= 623 / 616

= 623

Step2:

LCM(7, 87) = 609

GCD(7, 87) = ( 7 x 87 ) / 609

= 7 / 87

= 7

Step3:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 623, 616, 87, 438 is 1
