GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 709) = 453051
GCD(639, 709) = ( 639 x 709 ) / 453051
= 639 / 709
= 639
Step2:
LCM(1, 739) = 739
GCD(1, 739) = ( 1 x 739 ) / 739
= 1 / 739
= 1
Step3:
LCM(1, 705) = 705
GCD(1, 705) = ( 1 x 705 ) / 705
= 1 / 705
= 1
So, Greatest Common Divisor of 639, 709, 739, 705 is 1
