Given numbers are 257, 188, 479, 634
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 188) = 48316
GCD(257, 188) = ( 257 x 188 ) / 48316
= 257 / 188
= 257
Step2:
LCM(1, 479) = 479
GCD(1, 479) = ( 1 x 479 ) / 479
= 1 / 479
= 1
Step3:
LCM(1, 634) = 634
GCD(1, 634) = ( 1 x 634 ) / 634
= 1 / 634
= 1
So, Greatest Common Divisor of 257, 188, 479, 634 is 1
