Given numbers are 545,154,249,970

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

The LCM of 545,154,249,970 is 2027161290.

Find LCM of 545,154,249,970 with Prime Factorization

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

2 x 5 x 109 x 77 x 249 x 97 = 2027161290

Therefore, the lowest common multiple of 545,154,249,970 is 2027161290.

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.

545 x 154 x 249 x 970 = 20271612900

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.

545 : 1, 5, 109, 545

154 : 1, 2, 7, 11, 14, 22, 77, 154

249 : 1, 3, 83, 249

970 : 1, 2, 5, 10, 97, 194, 485, 970

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,154,249,970, is 1.

Now, the common factors can be found like this.

545:5x 109

154:2x 7x 11

249:3x 83

970:2x 5x 97

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 = 20271612900/(1x10)

LCM = 20271612900/10

LCM = 2027161290

Thus, we can understand that the LCM of 545,154,249,970 is 2027161290.
