Given numbers are 478, 427, 81, 870

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

Apply this formula for all numbers.

Step1:

LCM(478, 427) = 204106

GCD(478, 427) = ( 478 x 427 ) / 204106

= 478 / 427

= 478

Step2:

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

= 1 / 81

= 1

Step3:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

So, Greatest Common Divisor of 478, 427, 81, 870 is 1
