Given numbers are 181, 687, 354, 972

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

Apply this formula for all numbers.

Step1:

LCM(181, 687) = 124347

GCD(181, 687) = ( 181 x 687 ) / 124347

= 181 / 687

= 181

Step2:

LCM(1, 354) = 354

GCD(1, 354) = ( 1 x 354 ) / 354

= 1 / 354

= 1

Step3:

LCM(1, 972) = 972

GCD(1, 972) = ( 1 x 972 ) / 972

= 1 / 972

= 1

So, Greatest Common Divisor of 181, 687, 354, 972 is 1
