Given numbers are 315, 471, 793, 690
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(315, 471) = 49455
GCD(315, 471) = ( 315 x 471 ) / 49455
= 315 / 471
= 315
Step2:
LCM(3, 793) = 2379
GCD(3, 793) = ( 3 x 793 ) / 2379
= 3 / 793
= 3
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 315, 471, 793, 690 is 1
