Given numbers are 661, 660, 456
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 660) = 436260
GCD(661, 660) = ( 661 x 660 ) / 436260
= 661 / 660
= 661
Step2:
LCM(1, 456) = 456
GCD(1, 456) = ( 1 x 456 ) / 456
= 1 / 456
= 1
So, Greatest Common Divisor of 661, 660, 456 is 1
