Given numbers are 690,201,642,580,651

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

The LCM of 690,201,642,580,651 is 62258033460.

Find LCM of 690,201,642,580,651 with Prime Factorization

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

2 x 3 x 5 x 23 x 67 x 107 x 58 x 217 = 62258033460

Therefore, the lowest common multiple of 690,201,642,580,651 is 62258033460.

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.

690 x 201 x 642 x 580 x 651 = 33619338068400

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

201 : 1, 3, 67, 201

642 : 1, 2, 3, 6, 107, 214, 321, 642

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

651 : 1, 3, 7, 21, 31, 93, 217, 651

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,201,642,580,651, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

201:3x 67

642:2x 3x 107

580:2x 2x 5x 29

651:3x 7x 31

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 3x 3x 3x 5 = 540

Therefore, the value for common factors is 540.

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 = 33619338068400/(1x540)

LCM = 33619338068400/540

LCM = 62258033460

Thus, we can understand that the LCM of 690,201,642,580,651 is 62258033460.
