Given numbers are 660, 644, 543, 838

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 543 are 3 x 181

Prime factors of 838 are 2 x 419

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

Given numbers are 660, 644, 543, 838

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

Apply this formula for all numbers.

Step1:

LCM(660, 644) = 106260

GCD(660, 644) = ( 660 x 644 ) / 106260

= 660 / 644

= 660

Step2:

LCM(4, 543) = 2172

GCD(4, 543) = ( 4 x 543 ) / 2172

= 4 / 543

= 4

Step3:

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

= 1 / 838

= 1

So, Greatest Common Divisor of 660, 644, 543, 838 is 1
