Given numbers are 394, 561, 100, 674
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(394, 561) = 221034
GCD(394, 561) = ( 394 x 561 ) / 221034
= 394 / 561
= 394
Step2:
LCM(1, 100) = 100
GCD(1, 100) = ( 1 x 100 ) / 100
= 1 / 100
= 1
Step3:
LCM(1, 674) = 674
GCD(1, 674) = ( 1 x 674 ) / 674
= 1 / 674
= 1
So, Greatest Common Divisor of 394, 561, 100, 674 is 1
