Given numbers are 221, 647, 764, 586
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 647) = 142987
GCD(221, 647) = ( 221 x 647 ) / 142987
= 221 / 647
= 221
Step2:
LCM(1, 764) = 764
GCD(1, 764) = ( 1 x 764 ) / 764
= 1 / 764
= 1
Step3:
LCM(1, 586) = 586
GCD(1, 586) = ( 1 x 586 ) / 586
= 1 / 586
= 1
So, Greatest Common Divisor of 221, 647, 764, 586 is 1
