GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 984) = 650424
GCD(661, 984) = ( 661 x 984 ) / 650424
= 661 / 984
= 661
Step2:
LCM(1, 980) = 980
GCD(1, 980) = ( 1 x 980 ) / 980
= 1 / 980
= 1
Step3:
LCM(1, 500) = 500
GCD(1, 500) = ( 1 x 500 ) / 500
= 1 / 500
= 1
So, Greatest Common Divisor of 661, 984, 980, 500 is 1
