Given numbers are 911, 138, 259, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(911, 138) = 125718
GCD(911, 138) = ( 911 x 138 ) / 125718
= 911 / 138
= 911
Step2:
LCM(1, 259) = 259
GCD(1, 259) = ( 1 x 259 ) / 259
= 1 / 259
= 1
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 911, 138, 259, 649 is 1
