GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 918) = 315792
GCD(688, 918) = ( 688 x 918 ) / 315792
= 688 / 918
= 688
Step2:
LCM(2, 372) = 372
GCD(2, 372) = ( 2 x 372 ) / 372
= 2 / 372
= 2
Step3:
LCM(2, 506) = 506
GCD(2, 506) = ( 2 x 506 ) / 506
= 2 / 506
= 2
So, Greatest Common Divisor of 688, 918, 372, 506 is 2
