Given numbers are 780, 515, 306
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 515) = 80340
GCD(780, 515) = ( 780 x 515 ) / 80340
= 780 / 515
= 780
Step2:
LCM(5, 306) = 1530
GCD(5, 306) = ( 5 x 306 ) / 1530
= 5 / 306
= 5
So, Greatest Common Divisor of 780, 515, 306 is 1
