Given numbers are 120, 879, 642, 787

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

Apply this formula for all numbers.

Step1:

LCM(120, 879) = 35160

GCD(120, 879) = ( 120 x 879 ) / 35160

= 120 / 879

= 120

Step2:

LCM(3, 642) = 642

GCD(3, 642) = ( 3 x 642 ) / 642

= 3 / 642

= 3

Step3:

LCM(3, 787) = 2361

GCD(3, 787) = ( 3 x 787 ) / 2361

= 3 / 787

= 3

So, Greatest Common Divisor of 120, 879, 642, 787 is 1
