Given numbers are 407, 478, 378, 164
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(407, 478) = 194546
GCD(407, 478) = ( 407 x 478 ) / 194546
= 407 / 478
= 407
Step2:
LCM(1, 378) = 378
GCD(1, 378) = ( 1 x 378 ) / 378
= 1 / 378
= 1
Step3:
LCM(1, 164) = 164
GCD(1, 164) = ( 1 x 164 ) / 164
= 1 / 164
= 1
So, Greatest Common Divisor of 407, 478, 378, 164 is 1
