Given numbers are 780, 808, 219, 412
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 808) = 157560
GCD(780, 808) = ( 780 x 808 ) / 157560
= 780 / 808
= 780
Step2:
LCM(4, 219) = 876
GCD(4, 219) = ( 4 x 219 ) / 876
= 4 / 219
= 4
Step3:
LCM(1, 412) = 412
GCD(1, 412) = ( 1 x 412 ) / 412
= 1 / 412
= 1
So, Greatest Common Divisor of 780, 808, 219, 412 is 1
