Given numbers are 120, 410, 688, 306
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(120, 410) = 4920
GCD(120, 410) = ( 120 x 410 ) / 4920
= 120 / 410
= 120
Step2:
LCM(10, 688) = 3440
GCD(10, 688) = ( 10 x 688 ) / 3440
= 10 / 688
= 10
Step3:
LCM(2, 306) = 306
GCD(2, 306) = ( 2 x 306 ) / 306
= 2 / 306
= 2
So, Greatest Common Divisor of 120, 410, 688, 306 is 2
