Given numbers are 515, 180, 486, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 180) = 18540
GCD(515, 180) = ( 515 x 180 ) / 18540
= 515 / 180
= 515
Step2:
LCM(5, 486) = 2430
GCD(5, 486) = ( 5 x 486 ) / 2430
= 5 / 486
= 5
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 515, 180, 486, 455 is 1
