Given numbers are 761, 138, 834, 621

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

Apply this formula for all numbers.

Step1:

LCM(761, 138) = 105018

GCD(761, 138) = ( 761 x 138 ) / 105018

= 761 / 138

= 761

Step2:

LCM(1, 834) = 834

GCD(1, 834) = ( 1 x 834 ) / 834

= 1 / 834

= 1

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 761, 138, 834, 621 is 1
