Given numbers are 872, 978, 633, 637
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(872, 978) = 426408
GCD(872, 978) = ( 872 x 978 ) / 426408
= 872 / 978
= 872
Step2:
LCM(2, 633) = 1266
GCD(2, 633) = ( 2 x 633 ) / 1266
= 2 / 633
= 2
Step3:
LCM(1, 637) = 637
GCD(1, 637) = ( 1 x 637 ) / 637
= 1 / 637
= 1
So, Greatest Common Divisor of 872, 978, 633, 637 is 1
