Given numbers are 312, 828, 55, 456

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

Apply this formula for all numbers.

Step1:

LCM(312, 828) = 21528

GCD(312, 828) = ( 312 x 828 ) / 21528

= 312 / 828

= 312

Step2:

LCM(12, 55) = 660

GCD(12, 55) = ( 12 x 55 ) / 660

= 12 / 55

= 12

Step3:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

So, Greatest Common Divisor of 312, 828, 55, 456 is 1
