Given numbers are 642, 244, 772, 237
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 244) = 78324
GCD(642, 244) = ( 642 x 244 ) / 78324
= 642 / 244
= 642
Step2:
LCM(2, 772) = 772
GCD(2, 772) = ( 2 x 772 ) / 772
= 2 / 772
= 2
Step3:
LCM(2, 237) = 474
GCD(2, 237) = ( 2 x 237 ) / 474
= 2 / 237
= 2
So, Greatest Common Divisor of 642, 244, 772, 237 is 1
