Given numbers are 770,128,115,753

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

The LCM of 770,128,115,753 is 853480320.

Find LCM of 770,128,115,753 with Prime Factorization

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

2 x 5 x 77 x 64 x 23 x 753 = 853480320

Therefore, the lowest common multiple of 770,128,115,753 is 853480320.

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 128 x 115 x 753 = 8534803200

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

128 : 1, 2, 4, 8, 16, 32, 64, 128

115 : 1, 5, 23, 115

753 : 1, 3, 251, 753

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,128,115,753, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

128:2x 2x 2x 2x 2x 2x 2

115:5x 23

753:3x 251

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 8534803200/(1x10)

LCM = 8534803200/10

LCM = 853480320

Thus, we can understand that the LCM of 770,128,115,753 is 853480320.
