Given numbers are 972, 639, 702, 955

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

Apply this formula for all numbers.

Step1:

LCM(972, 639) = 69012

GCD(972, 639) = ( 972 x 639 ) / 69012

= 972 / 639

= 972

Step2:

LCM(9, 702) = 702

GCD(9, 702) = ( 9 x 702 ) / 702

= 9 / 702

= 9

Step3:

LCM(9, 955) = 8595

GCD(9, 955) = ( 9 x 955 ) / 8595

= 9 / 955

= 9

So, Greatest Common Divisor of 972, 639, 702, 955 is 1
