Given numbers are 475,722,562,534,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 475,722,562,534,642 is 144903396450.
Find LCM of 475,722,562,534,642 with Prime Factorization
| 2 | 475, 722, 562, 534, 642 |
| 3 | 475, 361, 281, 267, 321 |
| 19 | 475, 361, 281, 89, 107 |
| 25, 19, 281, 89, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 25 x 19 x 281 x 89 x 107 = 144903396450
Therefore, the lowest common multiple of 475,722,562,534,642 is 144903396450.
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.
475 x 722 x 562 x 534 x 642 = 66075948781200
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.
475 : 1, 5, 19, 25, 95, 475
722 : 1, 2, 19, 38, 361, 722
562 : 1, 2, 281, 562
534 : 1, 2, 3, 6, 89, 178, 267, 534
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 475,722,562,534,642, is 1.
Now, the common factors can be found like this.
475:5x 5x 19
722:2x 19x 19
562:2x 281
534:2x 3x 89
642:2x 3x 107
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 3x 19 = 456
Therefore, the value for common factors is 456.
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 = 66075948781200/(1x456)
LCM = 66075948781200/456
LCM = 144903396450
Thus, we can understand that the LCM of 475,722,562,534,642 is 144903396450.
