GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(947, 855) = 809685
GCD(947, 855) = ( 947 x 855 ) / 809685
= 947 / 855
= 947
Step2:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
Step3:
LCM(1, 439) = 439
GCD(1, 439) = ( 1 x 439 ) / 439
= 1 / 439
= 1
So, Greatest Common Divisor of 947, 855, 621, 439 is 1
