Given numbers are 840, 690, 223, 140

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 690 are 2 x 3 x 5 x 23

Prime factors of 223 are 223

Prime factors of 140 are 2 x 2 x 5 x 7

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

Given numbers are 840, 690, 223, 140

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

Apply this formula for all numbers.

Step1:

LCM(840, 690) = 19320

GCD(840, 690) = ( 840 x 690 ) / 19320

= 840 / 690

= 840

Step2:

LCM(30, 223) = 6690

GCD(30, 223) = ( 30 x 223 ) / 6690

= 30 / 223

= 30

Step3:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

So, Greatest Common Divisor of 840, 690, 223, 140 is 1
