Given numbers are 155,691,407,143
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 155,691,407,143 is 566692555.
Find LCM of 155,691,407,143 with Prime Factorization
11 | 155, 691, 407, 143 |
155, 691, 37, 13 |
Multiply the prime numbers at the bottom and the left side.
11 x 155 x 691 x 37 x 13 = 566692555
Therefore, the lowest common multiple of 155,691,407,143 is 566692555.
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.
155 x 691 x 407 x 143 = 6233618105
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.
155 : 1, 5, 31, 155
691 : 1, 691
407 : 1, 11, 37, 407
143 : 1, 11, 13, 143
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,691,407,143, is 1.
Now, the common factors can be found like this.
155:5x 31
691:691
407:11x 37
143:11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 6233618105/(1x11)
LCM = 6233618105/11
LCM = 566692555
Thus, we can understand that the LCM of 155,691,407,143 is 566692555.
