Given numbers are 242, 781, 651, 972

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

Apply this formula for all numbers.

Step1:

LCM(242, 781) = 17182

GCD(242, 781) = ( 242 x 781 ) / 17182

= 242 / 781

= 242

Step2:

LCM(11, 651) = 7161

GCD(11, 651) = ( 11 x 651 ) / 7161

= 11 / 651

= 11

Step3:

LCM(1, 972) = 972

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

= 1 / 972

= 1

So, Greatest Common Divisor of 242, 781, 651, 972 is 1
