Given numbers are 251, 381, 148, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(251, 381) = 95631
GCD(251, 381) = ( 251 x 381 ) / 95631
= 251 / 381
= 251
Step2:
LCM(1, 148) = 148
GCD(1, 148) = ( 1 x 148 ) / 148
= 1 / 148
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 251, 381, 148, 689 is 1
