Given numbers are 690,149,146,745
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 690,149,146,745 is 7505130.
Find LCM of 690,149,146,745 with Prime Factorization
2 | 690, 149, 146, 745 |
5 | 345, 149, 73, 745 |
149 | 69, 149, 73, 149 |
69, 1, 73, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 149 x 69 x 1 x 73 x 1 = 7505130
Therefore, the lowest common multiple of 690,149,146,745 is 7505130.
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.
690 x 149 x 146 x 745 = 11182643700
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
149 : 1, 149
146 : 1, 2, 73, 146
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,149,146,745, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
149:149
146:2x 73
745:5x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 149 = 1490
Therefore, the value for common factors is 1490.
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 = 11182643700/(1x1490)
LCM = 11182643700/1490
LCM = 7505130
Thus, we can understand that the LCM of 690,149,146,745 is 7505130.
