Given numbers are 477, 143, 575, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(477, 143) = 68211
GCD(477, 143) = ( 477 x 143 ) / 68211
= 477 / 143
= 477
Step2:
LCM(1, 575) = 575
GCD(1, 575) = ( 1 x 575 ) / 575
= 1 / 575
= 1
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 477, 143, 575, 257 is 1
