The LCM of 803,260,611,440 is 19625320.
Find LCM of 803,260,611,440 with Prime Factorization
| 2 | 803, 260, 611, 440 |
| 2 | 803, 130, 611, 220 |
| 5 | 803, 65, 611, 110 |
| 11 | 803, 13, 611, 22 |
| 13 | 73, 13, 611, 2 |
| 73, 1, 47, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 13 x 73 x 1 x 47 x 2 = 19625320
Therefore, the lowest common multiple of 803,260,611,440 is 19625320.
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.
803 x 260 x 611 x 440 = 56128415200
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.
803 : 1, 11, 73, 803
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
611 : 1, 13, 47, 611
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,260,611,440, is 1.
Now, the common factors can be found like this.
803:11x 73
260:2x 2x 5x 13
611:13x 47
440:2x 2x 2x 5x 11
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 5x 11x 13 = 2860
Therefore, the value for common factors is 2860.
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 = 56128415200/(1x2860)
LCM = 56128415200/2860
LCM = 19625320
Thus, we can understand that the LCM of 803,260,611,440 is 19625320.
