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, 513) = 1026
GCD(2, 513) = ( 2 x 513 ) / 1026
= 2 / 513
= 2
Step3:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
So, Greatest Common Divisor of 688, 918, 513, 423 is 1
