Given numbers are 515, 610, 782, 691
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 610) = 62830
GCD(515, 610) = ( 515 x 610 ) / 62830
= 515 / 610
= 515
Step2:
LCM(5, 782) = 3910
GCD(5, 782) = ( 5 x 782 ) / 3910
= 5 / 782
= 5
Step3:
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
= 1 / 691
= 1
So, Greatest Common Divisor of 515, 610, 782, 691 is 1
