GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(409, 781) = 319429
GCD(409, 781) = ( 409 x 781 ) / 319429
= 409 / 781
= 409
Step2:
LCM(1, 944) = 944
GCD(1, 944) = ( 1 x 944 ) / 944
= 1 / 944
= 1
Step3:
LCM(1, 178) = 178
GCD(1, 178) = ( 1 x 178 ) / 178
= 1 / 178
= 1
So, Greatest Common Divisor of 409, 781, 944, 178 is 1
