Given numbers are 386, 478, 463, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(386, 478) = 92254
GCD(386, 478) = ( 386 x 478 ) / 92254
= 386 / 478
= 386
Step2:
LCM(2, 463) = 926
GCD(2, 463) = ( 2 x 463 ) / 926
= 2 / 463
= 2
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 386, 478, 463, 455 is 1
