Given numbers are 395, 123, 19, 402
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(395, 123) = 48585
GCD(395, 123) = ( 395 x 123 ) / 48585
= 395 / 123
= 395
Step2:
LCM(1, 19) = 19
GCD(1, 19) = ( 1 x 19 ) / 19
= 1 / 19
= 1
Step3:
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
= 1 / 402
= 1
So, Greatest Common Divisor of 395, 123, 19, 402 is 1
