Given numbers are 542, 538, 638, 147

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

Apply this formula for all numbers.

Step1:

LCM(542, 538) = 145798

GCD(542, 538) = ( 542 x 538 ) / 145798

= 542 / 538

= 542

Step2:

LCM(2, 638) = 638

GCD(2, 638) = ( 2 x 638 ) / 638

= 2 / 638

= 2

Step3:

LCM(2, 147) = 294

GCD(2, 147) = ( 2 x 147 ) / 294

= 2 / 147

= 2

So, Greatest Common Divisor of 542, 538, 638, 147 is 1
