Given numbers are 479, 125, 690, 393
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(479, 125) = 59875
GCD(479, 125) = ( 479 x 125 ) / 59875
= 479 / 125
= 479
Step2:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
Step3:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
So, Greatest Common Divisor of 479, 125, 690, 393 is 1
