Given numbers are 605,520,761,286
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,520,761,286 is 47882120.
Find LCM of 605,520,761,286 with Prime Factorization
| 2 | 605, 520, 761, 286 |
| 5 | 605, 260, 761, 143 |
| 11 | 121, 52, 761, 143 |
| 13 | 11, 52, 761, 13 |
| 11, 4, 761, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 13 x 11 x 4 x 761 x 1 = 47882120
Therefore, the lowest common multiple of 605,520,761,286 is 47882120.
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.
605 x 520 x 761 x 286 = 68471431600
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.
605 : 1, 5, 11, 55, 121, 605
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
761 : 1, 761
286 : 1, 2, 11, 13, 22, 26, 143, 286
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,520,761,286, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
520:2x 2x 2x 5x 13
761:761
286:2x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11x 13 = 1430
Therefore, the value for common factors is 1430.
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 = 68471431600/(1x1430)
LCM = 68471431600/1430
LCM = 47882120
Thus, we can understand that the LCM of 605,520,761,286 is 47882120.
