Given numbers are 348, 438, 393, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(348, 438) = 25404
GCD(348, 438) = ( 348 x 438 ) / 25404
= 348 / 438
= 348
Step2:
LCM(6, 393) = 786
GCD(6, 393) = ( 6 x 393 ) / 786
= 6 / 393
= 6
Step3:
LCM(3, 815) = 2445
GCD(3, 815) = ( 3 x 815 ) / 2445
= 3 / 815
= 3
So, Greatest Common Divisor of 348, 438, 393, 815 is 1
