Calculate the LCM of 445,749,640,807

Given numbers are 445,749,640,807

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

The LCM of 445,749,640,807 is 34429073280.

Find LCM of 445,749,640,807 with Prime Factorization


5 445, 749, 640, 807
89, 749, 128, 807

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

5 x 89 x 749 x 128 x 807 = 34429073280

Therefore, the lowest common multiple of 445,749,640,807 is 34429073280.

LCM Formula to Find Lowest Common Multiple of 445,749,640,807

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.

445 x 749 x 640 x 807 = 172145366400

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.

445 : 1, 5, 89, 445

749 : 1, 7, 107, 749

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

807 : 1, 3, 269, 807

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,749,640,807, is 1.

Now, the common factors can be found like this.

445:5x 89

749:7x 107

640:2x 2x 2x 2x 2x 2x 2x 5

807:3x 269

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

5 = 5

Therefore, the value for common factors is 5.

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 = 172145366400/(1x5)

LCM = 172145366400/5

LCM = 34429073280

Thus, we can understand that the LCM of 445,749,640,807 is 34429073280.
