Given numbers are 515, 689, 343, 658
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 689) = 354835
GCD(515, 689) = ( 515 x 689 ) / 354835
= 515 / 689
= 515
Step2:
LCM(1, 343) = 343
GCD(1, 343) = ( 1 x 343 ) / 343
= 1 / 343
= 1
Step3:
LCM(1, 658) = 658
GCD(1, 658) = ( 1 x 658 ) / 658
= 1 / 658
= 1
So, Greatest Common Divisor of 515, 689, 343, 658 is 1
