Given numbers are 778,357,658,307
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,357,658,307 is 4007597034.
Find LCM of 778,357,658,307 with Prime Factorization
| 2 | 778, 357, 658, 307 |
| 7 | 389, 357, 329, 307 |
| 389, 51, 47, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 389 x 51 x 47 x 307 = 4007597034
Therefore, the lowest common multiple of 778,357,658,307 is 4007597034.
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 357 x 658 x 307 = 56106358476
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
357 : 1, 3, 7, 17, 21, 51, 119, 357
658 : 1, 2, 7, 14, 47, 94, 329, 658
307 : 1, 307
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,357,658,307, is 1.
Now, the common factors can be found like this.
778:2x 389
357:3x 7x 17
658:2x 7x 47
307:307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 56106358476/(1x14)
LCM = 56106358476/14
LCM = 4007597034
Thus, we can understand that the LCM of 778,357,658,307 is 4007597034.
