Find LCM of 447,870,477,360,644 with Prime Factorization


2 447, 870, 477, 360, 644
2 447, 435, 477, 180, 322
3 447, 435, 477, 90, 161
3 149, 145, 159, 30, 161
5 149, 145, 53, 10, 161
149, 29, 53, 2, 161

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

2 x 2 x 3 x 3 x 5 x 149 x 29 x 53 x 2 x 161 = 13273593480

Therefore, the lowest common multiple of 447,870,477,360,644 is 13273593480.

LCM Formula to Find Lowest Common Multiple of 447,870,477,360,644

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.

447 x 870 x 477 x 360 x 644 = 43006442875200

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.

447 : 1, 3, 149, 447

870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870

477 : 1, 3, 9, 53, 159, 477

360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,870,477,360,644, is 1.

Now, the common factors can be found like this.

447:3x 149

870:2x 3x 5x 29

477:3x 3x 53

360:2x 2x 2x 3x 3x 5

644:2x 2x 7x 23

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 2x 3x 3x 3x 3x 5 = 3240

Therefore, the value for common factors is 3240.

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 = 43006442875200/(1x3240)

LCM = 43006442875200/3240

LCM = 13273593480

Thus, we can understand that the LCM of 447,870,477,360,644 is 13273593480.
