Given numbers are 686, 202, 646, 807
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 202) = 69286
GCD(686, 202) = ( 686 x 202 ) / 69286
= 686 / 202
= 686
Step2:
LCM(2, 646) = 646
GCD(2, 646) = ( 2 x 646 ) / 646
= 2 / 646
= 2
Step3:
LCM(2, 807) = 1614
GCD(2, 807) = ( 2 x 807 ) / 1614
= 2 / 807
= 2
So, Greatest Common Divisor of 686, 202, 646, 807 is 1
