Given numbers are 639, 544, 557, 181

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

Apply this formula for all numbers.

Step1:

LCM(639, 544) = 347616

GCD(639, 544) = ( 639 x 544 ) / 347616

= 639 / 544

= 639

Step2:

LCM(1, 557) = 557

GCD(1, 557) = ( 1 x 557 ) / 557

= 1 / 557

= 1

Step3:

LCM(1, 181) = 181

GCD(1, 181) = ( 1 x 181 ) / 181

= 1 / 181

= 1

So, Greatest Common Divisor of 639, 544, 557, 181 is 1
