Given numbers are 802,221,748,330
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 802,221,748,330 is 58489860.
Find LCM of 802,221,748,330 with Prime Factorization
| 2 | 802, 221, 748, 330 |
| 11 | 401, 221, 374, 165 |
| 17 | 401, 221, 34, 15 |
| 401, 13, 2, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 401 x 13 x 2 x 15 = 58489860
Therefore, the lowest common multiple of 802,221,748,330 is 58489860.
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.
802 x 221 x 748 x 330 = 43750415280
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.
802 : 1, 2, 401, 802
221 : 1, 13, 17, 221
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,221,748,330, is 1.
Now, the common factors can be found like this.
802:2x 401
221:13x 17
748:2x 2x 11x 17
330:2x 3x 5x 11
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 11x 17 = 748
Therefore, the value for common factors is 748.
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 = 43750415280/(1x748)
LCM = 43750415280/748
LCM = 58489860
Thus, we can understand that the LCM of 802,221,748,330 is 58489860.
