Given numbers are 515, 390, 255, 669
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 390) = 40170
GCD(515, 390) = ( 515 x 390 ) / 40170
= 515 / 390
= 515
Step2:
LCM(5, 255) = 255
GCD(5, 255) = ( 5 x 255 ) / 255
= 5 / 255
= 5
Step3:
LCM(5, 669) = 3345
GCD(5, 669) = ( 5 x 669 ) / 3345
= 5 / 669
= 5
So, Greatest Common Divisor of 515, 390, 255, 669 is 1
