Given numbers are 374,642,970,722,722
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 374,642,970,722,722 is 21019654590.
Find LCM of 374,642,970,722,722 with Prime Factorization
| 2 | 374, 642, 970, 722, 722 |
| 19 | 187, 321, 485, 361, 361 |
| 19 | 187, 321, 485, 19, 19 |
| 187, 321, 485, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 19 x 187 x 321 x 485 x 1 x 1 = 21019654590
Therefore, the lowest common multiple of 374,642,970,722,722 is 21019654590.
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.
374 x 642 x 970 x 722 x 722 = 121409524911840
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.
374 : 1, 2, 11, 17, 22, 34, 187, 374
642 : 1, 2, 3, 6, 107, 214, 321, 642
970 : 1, 2, 5, 10, 97, 194, 485, 970
722 : 1, 2, 19, 38, 361, 722
722 : 1, 2, 19, 38, 361, 722
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 374,642,970,722,722, is 2.
Now, the common factors can be found like this.
374:2x 11x 17
642:2x 3x 107
970:2x 5x 97
722:2x 19x 19
722:2x 19x 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 2x 2x 19x 19 = 2888
Therefore, the value for common factors is 2888.
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 = 121409524911840/(2x2888)
LCM = 121409524911840/5776
LCM = 21019654590
Thus, we can understand that the LCM of 374,642,970,722,722 is 21019654590.
