Given numbers are 108, 100, 661
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(108, 100) = 2700
GCD(108, 100) = ( 108 x 100 ) / 2700
= 108 / 100
= 108
Step2:
LCM(4, 661) = 2644
GCD(4, 661) = ( 4 x 661 ) / 2644
= 4 / 661
= 4
So, Greatest Common Divisor of 108, 100, 661 is 1
