Given numbers are 157, 678, 859, 621

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

Apply this formula for all numbers.

Step1:

LCM(157, 678) = 106446

GCD(157, 678) = ( 157 x 678 ) / 106446

= 157 / 678

= 157

Step2:

LCM(1, 859) = 859

GCD(1, 859) = ( 1 x 859 ) / 859

= 1 / 859

= 1

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 157, 678, 859, 621 is 1
