Given numbers are 706,921,453,436,216
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 706,921,453,436,216 is 385274510424.
Find LCM of 706,921,453,436,216 with Prime Factorization
| 2 | 706, 921, 453, 436, 216 |
| 2 | 353, 921, 453, 218, 108 |
| 3 | 353, 921, 453, 109, 54 |
| 353, 307, 151, 109, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 353 x 307 x 151 x 109 x 18 = 385274510424
Therefore, the lowest common multiple of 706,921,453,436,216 is 385274510424.
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.
706 x 921 x 453 x 436 x 216 = 27739764750528
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.
706 : 1, 2, 353, 706
921 : 1, 3, 307, 921
453 : 1, 3, 151, 453
436 : 1, 2, 4, 109, 218, 436
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 706,921,453,436,216, is 1.
Now, the common factors can be found like this.
706:2x 353
921:3x 307
453:3x 151
436:2x 2x 109
216:2x 2x 2x 3x 3x 3
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 3 = 72
Therefore, the value for common factors is 72.
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 = 27739764750528/(1x72)
LCM = 27739764750528/72
LCM = 385274510424
Thus, we can understand that the LCM of 706,921,453,436,216 is 385274510424.
