Calculate the LCM of 889,945,655,445

Given numbers are 889,945,655,445

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

The LCM of 889,945,655,445 is 1399254885.

Find LCM of 889,945,655,445 with Prime Factorization


5 889, 945, 655, 445
7 889, 189, 131, 89
127, 27, 131, 89

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

5 x 7 x 127 x 27 x 131 x 89 = 1399254885

Therefore, the lowest common multiple of 889,945,655,445 is 1399254885.

LCM Formula to Find Lowest Common Multiple of 889,945,655,445

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.

889 x 945 x 655 x 445 = 244869604875

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.

889 : 1, 7, 127, 889

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

655 : 1, 5, 131, 655

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 889,945,655,445, is 1.

Now, the common factors can be found like this.

889:7x 127

945:3x 3x 3x 5x 7

655:5x 131

445:5x 89

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

5x 5x 7 = 175

Therefore, the value for common factors is 175.

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 = 244869604875/(1x175)

LCM = 244869604875/175

LCM = 1399254885

Thus, we can understand that the LCM of 889,945,655,445 is 1399254885.
