Given numbers are 649, 812, 743, 761

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

Apply this formula for all numbers.

Step1:

LCM(649, 812) = 526988

GCD(649, 812) = ( 649 x 812 ) / 526988

= 649 / 812

= 649

Step2:

LCM(1, 743) = 743

GCD(1, 743) = ( 1 x 743 ) / 743

= 1 / 743

= 1

Step3:

LCM(1, 761) = 761

GCD(1, 761) = ( 1 x 761 ) / 761

= 1 / 761

= 1

So, Greatest Common Divisor of 649, 812, 743, 761 is 1
