Given numbers are 778,484,655,508,320
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,484,655,508,320 is 250587824960.
Find LCM of 778,484,655,508,320 with Prime Factorization
| 2 | 778, 484, 655, 508, 320 |
| 2 | 389, 242, 655, 254, 160 |
| 5 | 389, 121, 655, 127, 80 |
| 389, 121, 131, 127, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 389 x 121 x 131 x 127 x 16 = 250587824960
Therefore, the lowest common multiple of 778,484,655,508,320 is 250587824960.
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.
778 x 484 x 655 x 508 x 320 = 40094051993600
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.
778 : 1, 2, 389, 778
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
655 : 1, 5, 131, 655
508 : 1, 2, 4, 127, 254, 508
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,484,655,508,320, is 1.
Now, the common factors can be found like this.
778:2x 389
484:2x 2x 11x 11
655:5x 131
508:2x 2x 127
320:2x 2x 2x 2x 2x 2x 5
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 2x 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 40094051993600/(1x160)
LCM = 40094051993600/160
LCM = 250587824960
Thus, we can understand that the LCM of 778,484,655,508,320 is 250587824960.
