Given numbers are 478, 686, 355, 910
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 686) = 163954
GCD(478, 686) = ( 478 x 686 ) / 163954
= 478 / 686
= 478
Step2:
LCM(2, 355) = 710
GCD(2, 355) = ( 2 x 355 ) / 710
= 2 / 355
= 2
Step3:
LCM(1, 910) = 910
GCD(1, 910) = ( 1 x 910 ) / 910
= 1 / 910
= 1
So, Greatest Common Divisor of 478, 686, 355, 910 is 1
