Given numbers are 147, 171, 74, 862

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

Apply this formula for all numbers.

Step1:

LCM(147, 171) = 8379

GCD(147, 171) = ( 147 x 171 ) / 8379

= 147 / 171

= 147

Step2:

LCM(3, 74) = 222

GCD(3, 74) = ( 3 x 74 ) / 222

= 3 / 74

= 3

Step3:

LCM(1, 862) = 862

GCD(1, 862) = ( 1 x 862 ) / 862

= 1 / 862

= 1

So, Greatest Common Divisor of 147, 171, 74, 862 is 1
