Given numbers are 520, 156, 851, 686
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(520, 156) = 1560
GCD(520, 156) = ( 520 x 156 ) / 1560
= 520 / 156
= 520
Step2:
LCM(52, 851) = 44252
GCD(52, 851) = ( 52 x 851 ) / 44252
= 52 / 851
= 52
Step3:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
So, Greatest Common Divisor of 520, 156, 851, 686 is 1
