Given numbers are 585, 931, 915, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(585, 931) = 544635
GCD(585, 931) = ( 585 x 931 ) / 544635
= 585 / 931
= 585
Step2:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
Step3:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
So, Greatest Common Divisor of 585, 931, 915, 687 is 1
