Given numbers are 694, 247, 240, 261
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(694, 247) = 171418
GCD(694, 247) = ( 694 x 247 ) / 171418
= 694 / 247
= 694
Step2:
LCM(1, 240) = 240
GCD(1, 240) = ( 1 x 240 ) / 240
= 1 / 240
= 1
Step3:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
So, Greatest Common Divisor of 694, 247, 240, 261 is 1
