Given numbers are 611, 650, 391, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(611, 650) = 30550
GCD(611, 650) = ( 611 x 650 ) / 30550
= 611 / 650
= 611
Step2:
LCM(13, 391) = 5083
GCD(13, 391) = ( 13 x 391 ) / 5083
= 13 / 391
= 13
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 611, 650, 391, 646 is 1
