Given numbers are 778,770,694,117,308
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,770,694,117,308 is 24321236940.
Find LCM of 778,770,694,117,308 with Prime Factorization
| 2 | 778, 770, 694, 117, 308 |
| 7 | 389, 385, 347, 117, 154 |
| 11 | 389, 55, 347, 117, 22 |
| 389, 5, 347, 117, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 389 x 5 x 347 x 117 x 2 = 24321236940
Therefore, the lowest common multiple of 778,770,694,117,308 is 24321236940.
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 770 x 694 x 117 x 308 = 14981881955040
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
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
694 : 1, 2, 347, 694
117 : 1, 3, 9, 13, 39, 117
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,770,694,117,308, is 1.
Now, the common factors can be found like this.
778:2x 389
770:2x 5x 7x 11
694:2x 347
117:3x 3x 13
308:2x 2x 7x 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 2x 7x 11 = 616
Therefore, the value for common factors is 616.
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 = 14981881955040/(1x616)
LCM = 14981881955040/616
LCM = 24321236940
Thus, we can understand that the LCM of 778,770,694,117,308 is 24321236940.
