Given numbers are 905,430,698,749

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

The LCM of 905,430,698,749 is 20344839830.

Find LCM of 905,430,698,749 with Prime Factorization

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

2 x 5 x 181 x 43 x 349 x 749 = 20344839830

Therefore, the lowest common multiple of 905,430,698,749 is 20344839830.

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.

905 x 430 x 698 x 749 = 203448398300

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.

905 : 1, 5, 181, 905

430 : 1, 2, 5, 10, 43, 86, 215, 430

698 : 1, 2, 349, 698

749 : 1, 7, 107, 749

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,430,698,749, is 1.

Now, the common factors can be found like this.

905:5x 181

430:2x 5x 43

698:2x 349

749:7x 107

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 = 203448398300/(1x10)

LCM = 203448398300/10

LCM = 20344839830

Thus, we can understand that the LCM of 905,430,698,749 is 20344839830.
