Given numbers are 408, 992, 145, 756

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

Apply this formula for all numbers.

Step1:

LCM(408, 992) = 50592

GCD(408, 992) = ( 408 x 992 ) / 50592

= 408 / 992

= 408

Step2:

LCM(8, 145) = 1160

GCD(8, 145) = ( 8 x 145 ) / 1160

= 8 / 145

= 8

Step3:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

So, Greatest Common Divisor of 408, 992, 145, 756 is 1
