Given numbers are 722,673,695,215,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,673,695,215,988 is 377553821060.
Find LCM of 722,673,695,215,988 with Prime Factorization
| 2 | 722, 673, 695, 215, 988 |
| 5 | 361, 673, 695, 215, 494 |
| 19 | 361, 673, 139, 43, 494 |
| 19, 673, 139, 43, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 19 x 673 x 139 x 43 x 26 = 377553821060
Therefore, the lowest common multiple of 722,673,695,215,988 is 377553821060.
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.
722 x 673 x 695 x 215 x 988 = 71735226001400
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.
722 : 1, 2, 19, 38, 361, 722
673 : 1, 673
695 : 1, 5, 139, 695
215 : 1, 5, 43, 215
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,673,695,215,988, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
673:673
695:5x 139
215:5x 43
988:2x 2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 19 = 190
Therefore, the value for common factors is 190.
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 = 71735226001400/(1x190)
LCM = 71735226001400/190
LCM = 377553821060
Thus, we can understand that the LCM of 722,673,695,215,988 is 377553821060.
