Given numbers are 246, 117, 143, 638

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

Apply this formula for all numbers.

Step1:

LCM(246, 117) = 9594

GCD(246, 117) = ( 246 x 117 ) / 9594

= 246 / 117

= 246

Step2:

LCM(3, 143) = 429

GCD(3, 143) = ( 3 x 143 ) / 429

= 3 / 143

= 3

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 246, 117, 143, 638 is 1
