Given numbers are 642, 834, 816, 307
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 834) = 89238
GCD(642, 834) = ( 642 x 834 ) / 89238
= 642 / 834
= 642
Step2:
LCM(6, 816) = 816
GCD(6, 816) = ( 6 x 816 ) / 816
= 6 / 816
= 6
Step3:
LCM(6, 307) = 1842
GCD(6, 307) = ( 6 x 307 ) / 1842
= 6 / 307
= 6
So, Greatest Common Divisor of 642, 834, 816, 307 is 1
