Given numbers are 745,561,534,980,169
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 745,561,534,980,169 is 1232116906020.
Find LCM of 745,561,534,980,169 with Prime Factorization
| 2 | 745, 561, 534, 980, 169 |
| 3 | 745, 561, 267, 490, 169 |
| 5 | 745, 187, 89, 490, 169 |
| 149, 187, 89, 98, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 149 x 187 x 89 x 98 x 169 = 1232116906020
Therefore, the lowest common multiple of 745,561,534,980,169 is 1232116906020.
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.
745 x 561 x 534 x 980 x 169 = 36963507180600
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.
745 : 1, 5, 149, 745
561 : 1, 3, 11, 17, 33, 51, 187, 561
534 : 1, 2, 3, 6, 89, 178, 267, 534
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
169 : 1, 13, 169
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,561,534,980,169, is 1.
Now, the common factors can be found like this.
745:5x 149
561:3x 11x 17
534:2x 3x 89
980:2x 2x 5x 7x 7
169:13x 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 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 36963507180600/(1x30)
LCM = 36963507180600/30
LCM = 1232116906020
Thus, we can understand that the LCM of 745,561,534,980,169 is 1232116906020.
