GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 924) = 87780
GCD(665, 924) = ( 665 x 924 ) / 87780
= 665 / 924
= 665
Step2:
LCM(7, 272) = 1904
GCD(7, 272) = ( 7 x 272 ) / 1904
= 7 / 272
= 7
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 665, 924, 272, 638 is 1
