Given numbers are 278,286,994,994,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,286,994,994,742 is 1047160114.
Find LCM of 278,286,994,994,742 with Prime Factorization
2 | 278, 286, 994, 994, 742 |
7 | 139, 143, 497, 497, 371 |
71 | 139, 143, 71, 71, 53 |
139, 143, 1, 1, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 71 x 139 x 143 x 1 x 1 x 53 = 1047160114
Therefore, the lowest common multiple of 278,286,994,994,742 is 1047160114.
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.
278 x 286 x 994 x 994 x 742 = 58289120585696
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.
278 : 1, 2, 139, 278
286 : 1, 2, 11, 13, 22, 26, 143, 286
994 : 1, 2, 7, 14, 71, 142, 497, 994
994 : 1, 2, 7, 14, 71, 142, 497, 994
742 : 1, 2, 7, 14, 53, 106, 371, 742
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,286,994,994,742, is 2.
Now, the common factors can be found like this.
278:2x 139
286:2x 11x 13
994:2x 7x 71
994:2x 7x 71
742:2x 7x 53
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 7x 71 = 27832
Therefore, the value for common factors is 27832.
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 = 58289120585696/(2x27832)
LCM = 58289120585696/55664
LCM = 1047160114
Thus, we can understand that the LCM of 278,286,994,994,742 is 1047160114.
