Given numbers are 700,121,455,221,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 700,121,455,221,715 is 18718700.
Find LCM of 700,121,455,221,715 with Prime Factorization
5 | 700, 121, 455, 221, 715 |
7 | 140, 121, 91, 221, 143 |
11 | 20, 121, 13, 221, 143 |
13 | 20, 11, 13, 221, 13 |
20, 11, 1, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 11 x 13 x 20 x 11 x 1 x 17 x 1 = 18718700
Therefore, the lowest common multiple of 700,121,455,221,715 is 18718700.
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.
700 x 121 x 455 x 221 x 715 = 6089661077500
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.
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
121 : 1, 11, 121
455 : 1, 5, 7, 13, 35, 65, 91, 455
221 : 1, 13, 17, 221
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 700,121,455,221,715, is 1.
Now, the common factors can be found like this.
700:2x 2x 5x 5x 7
121:11x 11
455:5x 7x 13
221:13x 17
715:5x 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.
5x 5x 7x 11x 13x 13 = 325325
Therefore, the value for common factors is 325325.
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 = 6089661077500/(1x325325)
LCM = 6089661077500/325325
LCM = 18718700
Thus, we can understand that the LCM of 700,121,455,221,715 is 18718700.
