Given numbers are 515, 485, 813, 158
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 485) = 49955
GCD(515, 485) = ( 515 x 485 ) / 49955
= 515 / 485
= 515
Step2:
LCM(5, 813) = 4065
GCD(5, 813) = ( 5 x 813 ) / 4065
= 5 / 813
= 5
Step3:
LCM(1, 158) = 158
GCD(1, 158) = ( 1 x 158 ) / 158
= 1 / 158
= 1
So, Greatest Common Divisor of 515, 485, 813, 158 is 1
