Given numbers are 448, 728, 862, 557

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(448, 728) = 5824

GCD(448, 728) = ( 448 x 728 ) / 5824

= 448 / 728

= 448

Step2:

LCM(56, 862) = 24136

GCD(56, 862) = ( 56 x 862 ) / 24136

= 56 / 862

= 56

Step3:

LCM(2, 557) = 1114

GCD(2, 557) = ( 2 x 557 ) / 1114

= 2 / 557

= 2

So, Greatest Common Divisor of 448, 728, 862, 557 is 1
