Given numbers are 515, 460, 196, 868
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 460) = 47380
GCD(515, 460) = ( 515 x 460 ) / 47380
= 515 / 460
= 515
Step2:
LCM(5, 196) = 980
GCD(5, 196) = ( 5 x 196 ) / 980
= 5 / 196
= 5
Step3:
LCM(1, 868) = 868
GCD(1, 868) = ( 1 x 868 ) / 868
= 1 / 868
= 1
So, Greatest Common Divisor of 515, 460, 196, 868 is 1
