Given numbers are 402, 321, 407, 194
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 321) = 43014
GCD(402, 321) = ( 402 x 321 ) / 43014
= 402 / 321
= 402
Step2:
LCM(3, 407) = 1221
GCD(3, 407) = ( 3 x 407 ) / 1221
= 3 / 407
= 3
Step3:
LCM(1, 194) = 194
GCD(1, 194) = ( 1 x 194 ) / 194
= 1 / 194
= 1
So, Greatest Common Divisor of 402, 321, 407, 194 is 1
