Given numbers are 778,429,220,186,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,429,220,186,242 is 1138128420.
Find LCM of 778,429,220,186,242 with Prime Factorization
| 2 | 778, 429, 220, 186, 242 |
| 3 | 389, 429, 110, 93, 121 |
| 11 | 389, 143, 110, 31, 121 |
| 389, 13, 10, 31, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 389 x 13 x 10 x 31 x 11 = 1138128420
Therefore, the lowest common multiple of 778,429,220,186,242 is 1138128420.
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 429 x 220 x 186 x 242 = 3305124931680
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
429 : 1, 3, 11, 13, 33, 39, 143, 429
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
186 : 1, 2, 3, 6, 31, 62, 93, 186
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,429,220,186,242, is 1.
Now, the common factors can be found like this.
778:2x 389
429:3x 11x 13
220:2x 2x 5x 11
186:2x 3x 31
242:2x 11x 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 3x 11x 11 = 2904
Therefore, the value for common factors is 2904.
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 = 3305124931680/(1x2904)
LCM = 3305124931680/2904
LCM = 1138128420
Thus, we can understand that the LCM of 778,429,220,186,242 is 1138128420.
