GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 610) = 209230
GCD(686, 610) = ( 686 x 610 ) / 209230
= 686 / 610
= 686
Step2:
LCM(2, 234) = 234
GCD(2, 234) = ( 2 x 234 ) / 234
= 2 / 234
= 2
Step3:
LCM(2, 520) = 520
GCD(2, 520) = ( 2 x 520 ) / 520
= 2 / 520
= 2
So, Greatest Common Divisor of 686, 610, 234, 520 is 2
