Given numbers are 778,121,758,607
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,121,758,607 is 21656729314.
Find LCM of 778,121,758,607 with Prime Factorization
| 2 | 778, 121, 758, 607 |
| 389, 121, 379, 607 |
Multiply the prime numbers at the bottom and the left side.
2 x 389 x 121 x 379 x 607 = 21656729314
Therefore, the lowest common multiple of 778,121,758,607 is 21656729314.
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 121 x 758 x 607 = 43313458628
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
121 : 1, 11, 121
758 : 1, 2, 379, 758
607 : 1, 607
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,121,758,607, is 1.
Now, the common factors can be found like this.
778:2x 389
121:11x 11
758:2x 379
607:607
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 43313458628/(1x2)
LCM = 43313458628/2
LCM = 21656729314
Thus, we can understand that the LCM of 778,121,758,607 is 21656729314.
