Given numbers are 315, 840, 349, 457
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(315, 840) = 2520
GCD(315, 840) = ( 315 x 840 ) / 2520
= 315 / 840
= 315
Step2:
LCM(105, 349) = 36645
GCD(105, 349) = ( 105 x 349 ) / 36645
= 105 / 349
= 105
Step3:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
So, Greatest Common Divisor of 315, 840, 349, 457 is 1
