Given numbers are 257, 142, 920, 444
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 142) = 36494
GCD(257, 142) = ( 257 x 142 ) / 36494
= 257 / 142
= 257
Step2:
LCM(1, 920) = 920
GCD(1, 920) = ( 1 x 920 ) / 920
= 1 / 920
= 1
Step3:
LCM(1, 444) = 444
GCD(1, 444) = ( 1 x 444 ) / 444
= 1 / 444
= 1
So, Greatest Common Divisor of 257, 142, 920, 444 is 1
