Given numbers are 972, 655, 78, 181

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

Apply this formula for all numbers.

Step1:

LCM(972, 655) = 636660

GCD(972, 655) = ( 972 x 655 ) / 636660

= 972 / 655

= 972

Step2:

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

= 1 / 78

= 1

Step3:

LCM(1, 181) = 181

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

= 1 / 181

= 1

So, Greatest Common Divisor of 972, 655, 78, 181 is 1
