GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(682, 862) = 293942
GCD(682, 862) = ( 682 x 862 ) / 293942
= 682 / 862
= 682
Step2:
LCM(2, 546) = 546
GCD(2, 546) = ( 2 x 546 ) / 546
= 2 / 546
= 2
Step3:
LCM(2, 390) = 390
GCD(2, 390) = ( 2 x 390 ) / 390
= 2 / 390
= 2
So, Greatest Common Divisor of 682, 862, 546, 390 is 2
