Given numbers are 642,749,107,563

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

The LCM of 642,749,107,563 is 2530122.

Find LCM of 642,749,107,563 with Prime Factorization

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

107 x 6 x 7 x 1 x 563 = 2530122

Therefore, the lowest common multiple of 642,749,107,563 is 2530122.

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.

642 x 749 x 107 x 563 = 28967366778

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.

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

749 : 1, 7, 107, 749

107 : 1, 107

563 : 1, 563

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,749,107,563, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

749:7x 107

107:107

563:563

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

107x 107 = 11449

Therefore, the value for common factors is 11449.

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 = 28967366778/(1x11449)

LCM = 28967366778/11449

LCM = 2530122

Thus, we can understand that the LCM of 642,749,107,563 is 2530122.
