GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(214, 155) = 33170
GCD(214, 155) = ( 214 x 155 ) / 33170
= 214 / 155
= 214
Step2:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
So, Greatest Common Divisor of 214, 155, 661 is 1
