Given numbers are 220,121,723,136,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,121,723,136,715 is 773349720.
Find LCM of 220,121,723,136,715 with Prime Factorization
| 2 | 220, 121, 723, 136, 715 |
| 2 | 110, 121, 723, 68, 715 |
| 5 | 55, 121, 723, 34, 715 |
| 11 | 11, 121, 723, 34, 143 |
| 1, 11, 723, 34, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 1 x 11 x 723 x 34 x 13 = 773349720
Therefore, the lowest common multiple of 220,121,723,136,715 is 773349720.
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.
220 x 121 x 723 x 136 x 715 = 1871506322400
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
121 : 1, 11, 121
723 : 1, 3, 241, 723
136 : 1, 2, 4, 8, 17, 34, 68, 136
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 220,121,723,136,715, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
121:11x 11
723:3x 241
136:2x 2x 2x 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.
2x 2x 5x 11x 11 = 2420
Therefore, the value for common factors is 2420.
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 = 1871506322400/(1x2420)
LCM = 1871506322400/2420
LCM = 773349720
Thus, we can understand that the LCM of 220,121,723,136,715 is 773349720.
