Given numbers are 780, 627, 978, 250
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 627) = 163020
GCD(780, 627) = ( 780 x 627 ) / 163020
= 780 / 627
= 780
Step2:
LCM(3, 978) = 978
GCD(3, 978) = ( 3 x 978 ) / 978
= 3 / 978
= 3
Step3:
LCM(3, 250) = 750
GCD(3, 250) = ( 3 x 250 ) / 750
= 3 / 250
= 3
So, Greatest Common Divisor of 780, 627, 978, 250 is 1
