Given numbers are 687, 822, 276, 431
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 822) = 188238
GCD(687, 822) = ( 687 x 822 ) / 188238
= 687 / 822
= 687
Step2:
LCM(3, 276) = 276
GCD(3, 276) = ( 3 x 276 ) / 276
= 3 / 276
= 3
Step3:
LCM(3, 431) = 1293
GCD(3, 431) = ( 3 x 431 ) / 1293
= 3 / 431
= 3
So, Greatest Common Divisor of 687, 822, 276, 431 is 1
