Given numbers are 840, 300, 570, 441

The list of prime factors of all numbers are

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 300 are 2 x 2 x 3 x 5 x 5

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 441 are 3 x 3 x 7 x 7

The highest common occurrence is 3¹

Therefore, GCD of 840, 300, 570, 441 is 3.

Given numbers are 840, 300, 570, 441

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

Apply this formula for all numbers.

Step1:

LCM(840, 300) = 4200

GCD(840, 300) = ( 840 x 300 ) / 4200

= 840 / 300

= 840

Step2:

LCM(60, 570) = 1140

GCD(60, 570) = ( 60 x 570 ) / 1140

= 60 / 570

= 60

Step3:

LCM(30, 441) = 4410

GCD(30, 441) = ( 30 x 441 ) / 4410

= 30 / 441

= 30

So, Greatest Common Divisor of 840, 300, 570, 441 is 3
