Given numbers are 785, 240, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(785, 240) = 37680
GCD(785, 240) = ( 785 x 240 ) / 37680
= 785 / 240
= 785
Step2:
LCM(5, 646) = 3230
GCD(5, 646) = ( 5 x 646 ) / 3230
= 5 / 646
= 5
So, Greatest Common Divisor of 785, 240, 646 is 1
