Given numbers are 581, 931, 406, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(581, 931) = 77273
GCD(581, 931) = ( 581 x 931 ) / 77273
= 581 / 931
= 581
Step2:
LCM(7, 406) = 406
GCD(7, 406) = ( 7 x 406 ) / 406
= 7 / 406
= 7
Step3:
LCM(7, 646) = 4522
GCD(7, 646) = ( 7 x 646 ) / 4522
= 7 / 646
= 7
So, Greatest Common Divisor of 581, 931, 406, 646 is 1
