Given numbers are 649, 145, 581, 583

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

Apply this formula for all numbers.

Step1:

LCM(649, 145) = 94105

GCD(649, 145) = ( 649 x 145 ) / 94105

= 649 / 145

= 649

Step2:

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

= 1 / 581

= 1

Step3:

LCM(1, 583) = 583

GCD(1, 583) = ( 1 x 583 ) / 583

= 1 / 583

= 1

So, Greatest Common Divisor of 649, 145, 581, 583 is 1
