Calculate the LCM of 890,700,542,430

Given numbers are 890,700,542,430

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

The LCM of 890,700,542,430 is 725981900.

Find LCM of 890,700,542,430 with Prime Factorization


2 890, 700, 542, 430
5 445, 350, 271, 215
89, 70, 271, 43

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

2 x 5 x 89 x 70 x 271 x 43 = 725981900

Therefore, the lowest common multiple of 890,700,542,430 is 725981900.

LCM Formula to Find Lowest Common Multiple of 890,700,542,430

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.

890 x 700 x 542 x 430 = 145196380000

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.

890 : 1, 2, 5, 10, 89, 178, 445, 890

700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700

542 : 1, 2, 271, 542

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,700,542,430, is 2.

Now, the common factors can be found like this.

890:2x 5x 89

700:2x 2x 5x 5x 7

542:2x 271

430:2x 5x 43

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 5x 5 = 100

Therefore, the value for common factors is 100.

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 = 145196380000/(2x100)

LCM = 145196380000/200

LCM = 725981900

Thus, we can understand that the LCM of 890,700,542,430 is 725981900.
