Given numbers are 761, 243, 899, 645

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

Apply this formula for all numbers.

Step1:

LCM(761, 243) = 184923

GCD(761, 243) = ( 761 x 243 ) / 184923

= 761 / 243

= 761

Step2:

LCM(1, 899) = 899

GCD(1, 899) = ( 1 x 899 ) / 899

= 1 / 899

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 761, 243, 899, 645 is 1
