Given numbers are 545,700,745,436,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 545,700,745,436,690 is 784440300.
Find LCM of 545,700,745,436,690 with Prime Factorization
| 2 | 545, 700, 745, 436, 690 |
| 2 | 545, 350, 745, 218, 345 |
| 5 | 545, 175, 745, 109, 345 |
| 109 | 109, 35, 149, 109, 69 |
| 1, 35, 149, 1, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 109 x 1 x 35 x 149 x 1 x 69 = 784440300
Therefore, the lowest common multiple of 545,700,745,436,690 is 784440300.
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.
545 x 700 x 745 x 436 x 690 = 85503992700000
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.
545 : 1, 5, 109, 545
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
745 : 1, 5, 149, 745
436 : 1, 2, 4, 109, 218, 436
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,700,745,436,690, is 1.
Now, the common factors can be found like this.
545:5x 109
700:2x 2x 5x 5x 7
745:5x 149
436:2x 2x 109
690:2x 3x 5x 23
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 2x 5x 5x 5x 109 = 109000
Therefore, the value for common factors is 109000.
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 = 85503992700000/(1x109000)
LCM = 85503992700000/109000
LCM = 784440300
Thus, we can understand that the LCM of 545,700,745,436,690 is 784440300.
