GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(756, 855) = 71820

GCD(756, 855) = ( 756 x 855 ) / 71820

= 756 / 855

= 756


Step2:

LCM(9, 520) = 4680

GCD(9, 520) = ( 9 x 520 ) / 4680

= 9 / 520

= 9


Step3:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1


So, Greatest Common Divisor of 756, 855, 520, 878 is 1
