Given numbers are 836, 649, 639, 674
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(836, 649) = 49324
GCD(836, 649) = ( 836 x 649 ) / 49324
= 836 / 649
= 836
Step2:
LCM(11, 639) = 7029
GCD(11, 639) = ( 11 x 639 ) / 7029
= 11 / 639
= 11
Step3:
LCM(1, 674) = 674
GCD(1, 674) = ( 1 x 674 ) / 674
= 1 / 674
= 1
So, Greatest Common Divisor of 836, 649, 639, 674 is 1
