GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 875) = 750750
GCD(858, 875) = ( 858 x 875 ) / 750750
= 858 / 875
= 858
Step2:
LCM(1, 635) = 635
GCD(1, 635) = ( 1 x 635 ) / 635
= 1 / 635
= 1
Step3:
LCM(1, 656) = 656
GCD(1, 656) = ( 1 x 656 ) / 656
= 1 / 656
= 1
So, Greatest Common Divisor of 858, 875, 635, 656 is 1
