Given numbers are 684, 579, 970, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(684, 579) = 132012
GCD(684, 579) = ( 684 x 579 ) / 132012
= 684 / 579
= 684
Step2:
LCM(3, 970) = 2910
GCD(3, 970) = ( 3 x 970 ) / 2910
= 3 / 970
= 3
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 684, 579, 970, 815 is 1
