Given numbers are 753,247,328,690,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 753,247,328,690,765 is 357794606520.
Find LCM of 753,247,328,690,765 with Prime Factorization
| 2 | 753, 247, 328, 690, 765 |
| 3 | 753, 247, 164, 345, 765 |
| 5 | 251, 247, 164, 115, 255 |
| 251, 247, 164, 23, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 251 x 247 x 164 x 23 x 51 = 357794606520
Therefore, the lowest common multiple of 753,247,328,690,765 is 357794606520.
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.
753 x 247 x 328 x 690 x 765 = 32201514586800
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.
753 : 1, 3, 251, 753
247 : 1, 13, 19, 247
328 : 1, 2, 4, 8, 41, 82, 164, 328
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 753,247,328,690,765, is 1.
Now, the common factors can be found like this.
753:3x 251
247:13x 19
328:2x 2x 2x 41
690:2x 3x 5x 23
765:3x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 32201514586800/(1x90)
LCM = 32201514586800/90
LCM = 357794606520
Thus, we can understand that the LCM of 753,247,328,690,765 is 357794606520.
