Given numbers are 644, 546, 519, 139

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

Apply this formula for all numbers.

Step1:

LCM(644, 546) = 25116

GCD(644, 546) = ( 644 x 546 ) / 25116

= 644 / 546

= 644

Step2:

LCM(14, 519) = 7266

GCD(14, 519) = ( 14 x 519 ) / 7266

= 14 / 519

= 14

Step3:

LCM(1, 139) = 139

GCD(1, 139) = ( 1 x 139 ) / 139

= 1 / 139

= 1

So, Greatest Common Divisor of 644, 546, 519, 139 is 1
