Given numbers are 666, 221, 416, 764
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(666, 221) = 147186
GCD(666, 221) = ( 666 x 221 ) / 147186
= 666 / 221
= 666
Step2:
LCM(1, 416) = 416
GCD(1, 416) = ( 1 x 416 ) / 416
= 1 / 416
= 1
Step3:
LCM(1, 764) = 764
GCD(1, 764) = ( 1 x 764 ) / 764
= 1 / 764
= 1
So, Greatest Common Divisor of 666, 221, 416, 764 is 1
