Given numbers are 697,358,720,670,851

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

The LCM of 697,358,720,670,851 is 5121800619120.

Find LCM of 697,358,720,670,851 with Prime Factorization

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

2 x 5 x 697 x 179 x 72 x 67 x 851 = 5121800619120

Therefore, the lowest common multiple of 697,358,720,670,851 is 5121800619120.

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.

697 x 358 x 720 x 670 x 851 = 102436012382400

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.

697 : 1, 17, 41, 697

358 : 1, 2, 179, 358

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

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

851 : 1, 23, 37, 851

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,358,720,670,851, is 1.

Now, the common factors can be found like this.

697:17x 41

358:2x 179

720:2x 2x 2x 2x 3x 3x 5

670:2x 5x 67

851:23x 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 5 = 20

Therefore, the value for common factors is 20.

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 = 102436012382400/(1x20)

LCM = 102436012382400/20

LCM = 5121800619120

Thus, we can understand that the LCM of 697,358,720,670,851 is 5121800619120.
