Given numbers are 686, 680, 802, 581
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 680) = 233240
GCD(686, 680) = ( 686 x 680 ) / 233240
= 686 / 680
= 686
Step2:
LCM(2, 802) = 802
GCD(2, 802) = ( 2 x 802 ) / 802
= 2 / 802
= 2
Step3:
LCM(2, 581) = 1162
GCD(2, 581) = ( 2 x 581 ) / 1162
= 2 / 581
= 2
So, Greatest Common Divisor of 686, 680, 802, 581 is 1
