Given numbers are 812, 690, 673, 585
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(812, 690) = 280140
GCD(812, 690) = ( 812 x 690 ) / 280140
= 812 / 690
= 812
Step2:
LCM(2, 673) = 1346
GCD(2, 673) = ( 2 x 673 ) / 1346
= 2 / 673
= 2
Step3:
LCM(1, 585) = 585
GCD(1, 585) = ( 1 x 585 ) / 585
= 1 / 585
= 1
So, Greatest Common Divisor of 812, 690, 673, 585 is 1
