Given numbers are 518, 118, 616, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(518, 118) = 30562
GCD(518, 118) = ( 518 x 118 ) / 30562
= 518 / 118
= 518
Step2:
LCM(2, 616) = 616
GCD(2, 616) = ( 2 x 616 ) / 616
= 2 / 616
= 2
Step3:
LCM(2, 257) = 514
GCD(2, 257) = ( 2 x 257 ) / 514
= 2 / 257
= 2
So, Greatest Common Divisor of 518, 118, 616, 257 is 1
