GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(659, 684) = 450756
GCD(659, 684) = ( 659 x 684 ) / 450756
= 659 / 684
= 659
Step2:
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
= 1 / 392
= 1
Step3:
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
= 1 / 905
= 1
So, Greatest Common Divisor of 659, 684, 392, 905 is 1
