Given numbers are 770,840,638,629

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

The LCM of 770,840,638,629 is 168546840.

Find LCM of 770,840,638,629 with Prime Factorization

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

2 x 5 x 7 x 11 x 1 x 12 x 29 x 629 = 168546840

Therefore, the lowest common multiple of 770,840,638,629 is 168546840.

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.

770 x 840 x 638 x 629 = 259562133600

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.

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

638 : 1, 2, 11, 22, 29, 58, 319, 638

629 : 1, 17, 37, 629

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,840,638,629, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

840:2x 2x 2x 3x 5x 7

638:2x 11x 29

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.

2x 2x 5x 7x 11 = 1540

Therefore, the value for common factors is 1540.

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 = 259562133600/(1x1540)

LCM = 259562133600/1540

LCM = 168546840

Thus, we can understand that the LCM of 770,840,638,629 is 168546840.
