Calculate the LCM of 157,391,440,629

Given numbers are 157,391,440,629

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

The LCM of 157,391,440,629 is 999380360.

Find LCM of 157,391,440,629 with Prime Factorization


17 157, 391, 440, 629
157, 23, 440, 37

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

17 x 157 x 23 x 440 x 37 = 999380360

Therefore, the lowest common multiple of 157,391,440,629 is 999380360.

LCM Formula to Find Lowest Common Multiple of 157,391,440,629

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.

157 x 391 x 440 x 629 = 16989466120

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.

157 : 1, 157

391 : 1, 17, 23, 391

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

629 : 1, 17, 37, 629

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,391,440,629, is 1.

Now, the common factors can be found like this.

157:157

391:17x 23

440:2x 2x 2x 5x 11

629:17x 37

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

17 = 17

Therefore, the value for common factors is 17.

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 = 16989466120/(1x17)

LCM = 16989466120/17

LCM = 999380360

Thus, we can understand that the LCM of 157,391,440,629 is 999380360.
