Given numbers are 513, 828, 455, 945

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

Apply this formula for all numbers.

Step1:

LCM(513, 828) = 47196

GCD(513, 828) = ( 513 x 828 ) / 47196

= 513 / 828

= 513

Step2:

LCM(9, 455) = 4095

GCD(9, 455) = ( 9 x 455 ) / 4095

= 9 / 455

= 9

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 513, 828, 455, 945 is 1
