Given numbers are 316, 172, 972, 655

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

Apply this formula for all numbers.

Step1:

LCM(316, 172) = 13588

GCD(316, 172) = ( 316 x 172 ) / 13588

= 316 / 172

= 316

Step2:

LCM(4, 972) = 972

GCD(4, 972) = ( 4 x 972 ) / 972

= 4 / 972

= 4

Step3:

LCM(4, 655) = 2620

GCD(4, 655) = ( 4 x 655 ) / 2620

= 4 / 655

= 4

So, Greatest Common Divisor of 316, 172, 972, 655 is 1
