Find LCM of 747,795,615,399,126 with Prime Factorization
| 3 | 747, 795, 615, 399, 126 |
| 3 | 249, 265, 205, 133, 42 |
| 5 | 83, 265, 205, 133, 14 |
| 7 | 83, 53, 41, 133, 14 |
| 83, 53, 41, 19, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 83 x 53 x 41 x 19 x 2 = 2158897230
Therefore, the lowest common multiple of 747,795,615,399,126 is 2158897230.
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.
747 x 795 x 615 x 399 x 126 = 18361420941150
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.
747 : 1, 3, 9, 83, 249, 747
795 : 1, 3, 5, 15, 53, 159, 265, 795
615 : 1, 3, 5, 15, 41, 123, 205, 615
399 : 1, 3, 7, 19, 21, 57, 133, 399
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,795,615,399,126, is 3.
Now, the common factors can be found like this.
747:3x 3x 83
795:3x 5x 53
615:3x 5x 41
399:3x 7x 19
126:2x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 5x 7 = 2835
Therefore, the value for common factors is 2835.
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 = 18361420941150/(3x2835)
LCM = 18361420941150/8505
LCM = 2158897230
Thus, we can understand that the LCM of 747,795,615,399,126 is 2158897230.
