Given numbers are 642, 179, 306, 348

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

Apply this formula for all numbers.

Step1:

LCM(642, 179) = 114918

GCD(642, 179) = ( 642 x 179 ) / 114918

= 642 / 179

= 642

Step2:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

Step3:

LCM(1, 348) = 348

GCD(1, 348) = ( 1 x 348 ) / 348

= 1 / 348

= 1

So, Greatest Common Divisor of 642, 179, 306, 348 is 1
