Given numbers are 442,901,767,553
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 442,901,767,553 is 764320102.
Find LCM of 442,901,767,553 with Prime Factorization
| 13 | 442, 901, 767, 553 |
| 17 | 34, 901, 59, 553 |
| 2, 53, 59, 553 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 2 x 53 x 59 x 553 = 764320102
Therefore, the lowest common multiple of 442,901,767,553 is 764320102.
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.
442 x 901 x 767 x 553 = 168914742542
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
901 : 1, 17, 53, 901
767 : 1, 13, 59, 767
553 : 1, 7, 79, 553
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,901,767,553, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
901:17x 53
767:13x 59
553:7x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 168914742542/(1x221)
LCM = 168914742542/221
LCM = 764320102
Thus, we can understand that the LCM of 442,901,767,553 is 764320102.
