Given numbers are 660, 770, 406, 860
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 770) = 4620
GCD(660, 770) = ( 660 x 770 ) / 4620
= 660 / 770
= 660
Step2:
LCM(110, 406) = 22330
GCD(110, 406) = ( 110 x 406 ) / 22330
= 110 / 406
= 110
Step3:
LCM(2, 860) = 860
GCD(2, 860) = ( 2 x 860 ) / 860
= 2 / 860
= 2
So, Greatest Common Divisor of 660, 770, 406, 860 is 2
