Given numbers are 653,440,319,649
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 653,440,319,649 is 491604520.
Find LCM of 653,440,319,649 with Prime Factorization
| 11 | 653, 440, 319, 649 |
| 653, 40, 29, 59 |
Multiply the prime numbers at the bottom and the left side.
11 x 653 x 40 x 29 x 59 = 491604520
Therefore, the lowest common multiple of 653,440,319,649 is 491604520.
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.
653 x 440 x 319 x 649 = 59484146920
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.
653 : 1, 653
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
319 : 1, 11, 29, 319
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 653,440,319,649, is 1.
Now, the common factors can be found like this.
653:653
440:2x 2x 2x 5x 11
319:11x 29
649:11x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 59484146920/(1x121)
LCM = 59484146920/121
LCM = 491604520
Thus, we can understand that the LCM of 653,440,319,649 is 491604520.
