Given numbers are 921, 840, 570, 236

The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

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

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

Prime factors of 236 are 2 x 2 x 59

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 921, 840, 570, 236

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

Apply this formula for all numbers.

Step1:

LCM(921, 840) = 257880

GCD(921, 840) = ( 921 x 840 ) / 257880

= 921 / 840

= 921

Step2:

LCM(3, 570) = 570

GCD(3, 570) = ( 3 x 570 ) / 570

= 3 / 570

= 3

Step3:

LCM(3, 236) = 708

GCD(3, 236) = ( 3 x 236 ) / 708

= 3 / 236

= 3

So, Greatest Common Divisor of 921, 840, 570, 236 is 1
