Given numbers are 637,890,628,644,892
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,890,628,644,892 is 913044166580.
Find LCM of 637,890,628,644,892 with Prime Factorization
| 2 | 637, 890, 628, 644, 892 |
| 2 | 637, 445, 314, 322, 446 |
| 7 | 637, 445, 157, 161, 223 |
| 91, 445, 157, 23, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 91 x 445 x 157 x 23 x 223 = 913044166580
Therefore, the lowest common multiple of 637,890,628,644,892 is 913044166580.
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.
637 x 890 x 628 x 644 x 892 = 204521893313920
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.
637 : 1, 7, 13, 49, 91, 637
890 : 1, 2, 5, 10, 89, 178, 445, 890
628 : 1, 2, 4, 157, 314, 628
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
892 : 1, 2, 4, 223, 446, 892
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,890,628,644,892, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
890:2x 5x 89
628:2x 2x 157
644:2x 2x 7x 23
892:2x 2x 223
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 2x 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 204521893313920/(1x224)
LCM = 204521893313920/224
LCM = 913044166580
Thus, we can understand that the LCM of 637,890,628,644,892 is 913044166580.
