Given numbers are 109, 431, 145, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(109, 431) = 46979
GCD(109, 431) = ( 109 x 431 ) / 46979
= 109 / 431
= 109
Step2:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
Step3:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
So, Greatest Common Divisor of 109, 431, 145, 247 is 1
