Given numbers are 669,721,740,670

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

The LCM of 669,721,740,670 is 23914863420.

Find LCM of 669,721,740,670 with Prime Factorization

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

2 x 5 x 669 x 721 x 74 x 67 = 23914863420

Therefore, the lowest common multiple of 669,721,740,670 is 23914863420.

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.

669 x 721 x 740 x 670 = 239148634200

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.

669 : 1, 3, 223, 669

721 : 1, 7, 103, 721

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

670 : 1, 2, 5, 10, 67, 134, 335, 670

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,721,740,670, is 1.

Now, the common factors can be found like this.

669:3x 223

721:7x 103

740:2x 2x 5x 37

670:2x 5x 67

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 = 239148634200/(1x10)

LCM = 239148634200/10

LCM = 23914863420

Thus, we can understand that the LCM of 669,721,740,670 is 23914863420.
