Given numbers are 837, 990, 109, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(837, 990) = 92070
GCD(837, 990) = ( 837 x 990 ) / 92070
= 837 / 990
= 837
Step2:
LCM(9, 109) = 981
GCD(9, 109) = ( 9 x 109 ) / 981
= 9 / 109
= 9
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 837, 990, 109, 646 is 1
