Given numbers are 155, 638, 705, 695
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 638) = 98890
GCD(155, 638) = ( 155 x 638 ) / 98890
= 155 / 638
= 155
Step2:
LCM(1, 705) = 705
GCD(1, 705) = ( 1 x 705 ) / 705
= 1 / 705
= 1
Step3:
LCM(1, 695) = 695
GCD(1, 695) = ( 1 x 695 ) / 695
= 1 / 695
= 1
So, Greatest Common Divisor of 155, 638, 705, 695 is 1
