Given numbers are 780, 344, 340, 959
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 344) = 67080
GCD(780, 344) = ( 780 x 344 ) / 67080
= 780 / 344
= 780
Step2:
LCM(4, 340) = 340
GCD(4, 340) = ( 4 x 340 ) / 340
= 4 / 340
= 4
Step3:
LCM(4, 959) = 3836
GCD(4, 959) = ( 4 x 959 ) / 3836
= 4 / 959
= 4
So, Greatest Common Divisor of 780, 344, 340, 959 is 1
