Given numbers are 905, 257, 413, 402
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(905, 257) = 232585
GCD(905, 257) = ( 905 x 257 ) / 232585
= 905 / 257
= 905
Step2:
LCM(1, 413) = 413
GCD(1, 413) = ( 1 x 413 ) / 413
= 1 / 413
= 1
Step3:
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
= 1 / 402
= 1
So, Greatest Common Divisor of 905, 257, 413, 402 is 1
