Given numbers are 140, 371, 261, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(140, 371) = 7420
GCD(140, 371) = ( 140 x 371 ) / 7420
= 140 / 371
= 140
Step2:
LCM(7, 261) = 1827
GCD(7, 261) = ( 7 x 261 ) / 1827
= 7 / 261
= 7
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 140, 371, 261, 689 is 1
