GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(392, 358) = 70168
GCD(392, 358) = ( 392 x 358 ) / 70168
= 392 / 358
= 392
Step2:
LCM(2, 723) = 1446
GCD(2, 723) = ( 2 x 723 ) / 1446
= 2 / 723
= 2
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 392, 358, 723, 561 is 1
