Given numbers are 431, 644, 292, 775
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(431, 644) = 277564
GCD(431, 644) = ( 431 x 644 ) / 277564
= 431 / 644
= 431
Step2:
LCM(1, 292) = 292
GCD(1, 292) = ( 1 x 292 ) / 292
= 1 / 292
= 1
Step3:
LCM(1, 775) = 775
GCD(1, 775) = ( 1 x 775 ) / 775
= 1 / 775
= 1
So, Greatest Common Divisor of 431, 644, 292, 775 is 1
