Given numbers are 780, 582, 850, 680
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 582) = 75660
GCD(780, 582) = ( 780 x 582 ) / 75660
= 780 / 582
= 780
Step2:
LCM(6, 850) = 2550
GCD(6, 850) = ( 6 x 850 ) / 2550
= 6 / 850
= 6
Step3:
LCM(2, 680) = 680
GCD(2, 680) = ( 2 x 680 ) / 680
= 2 / 680
= 2
So, Greatest Common Divisor of 780, 582, 850, 680 is 2
