Given numbers are 629,153,121,987

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 629,153,121,987 is 225358749.

Find LCM of 629,153,121,987 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

3 x 17 x 37 x 3 x 121 x 329 = 225358749

Therefore, the lowest common multiple of 629,153,121,987 is 225358749.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

629 x 153 x 121 x 987 = 11493296199

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

629 : 1, 17, 37, 629

153 : 1, 3, 9, 17, 51, 153

121 : 1, 11, 121

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 629,153,121,987, is 1.

Now, the common factors can be found like this.

629:17x 37

153:3x 3x 17

121:11x 11

987:3x 7x 47

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 17 = 51

Therefore, the value for common factors is 51.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 11493296199/(1x51)

LCM = 11493296199/51

LCM = 225358749

Thus, we can understand that the LCM of 629,153,121,987 is 225358749.
