Given numbers are 408, 428, 257, 112
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 428) = 43656
GCD(408, 428) = ( 408 x 428 ) / 43656
= 408 / 428
= 408
Step2:
LCM(4, 257) = 1028
GCD(4, 257) = ( 4 x 257 ) / 1028
= 4 / 257
= 4
Step3:
LCM(1, 112) = 112
GCD(1, 112) = ( 1 x 112 ) / 112
= 1 / 112
= 1
So, Greatest Common Divisor of 408, 428, 257, 112 is 1
