GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(409, 661) = 270349
GCD(409, 661) = ( 409 x 661 ) / 270349
= 409 / 661
= 409
Step2:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
Step3:
LCM(1, 194) = 194
GCD(1, 194) = ( 1 x 194 ) / 194
= 1 / 194
= 1
So, Greatest Common Divisor of 409, 661, 128, 194 is 1
