Given numbers are 768, 321, 850, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(768, 321) = 82176
GCD(768, 321) = ( 768 x 321 ) / 82176
= 768 / 321
= 768
Step2:
LCM(3, 850) = 2550
GCD(3, 850) = ( 3 x 850 ) / 2550
= 3 / 850
= 3
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 768, 321, 850, 646 is 1
