Given numbers are 170,690,411,621,475
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 170,690,411,621,475 is 1373993550.
Find LCM of 170,690,411,621,475 with Prime Factorization
| 2 | 170, 690, 411, 621, 475 |
| 3 | 85, 345, 411, 621, 475 |
| 5 | 85, 115, 137, 207, 475 |
| 23 | 17, 23, 137, 207, 95 |
| 17, 1, 137, 9, 95 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 17 x 1 x 137 x 9 x 95 = 1373993550
Therefore, the lowest common multiple of 170,690,411,621,475 is 1373993550.
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.
170 x 690 x 411 x 621 x 475 = 14220833242500
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.
170 : 1, 2, 5, 10, 17, 34, 85, 170
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
411 : 1, 3, 137, 411
621 : 1, 3, 9, 23, 27, 69, 207, 621
475 : 1, 5, 19, 25, 95, 475
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,690,411,621,475, is 1.
Now, the common factors can be found like this.
170:2x 5x 17
690:2x 3x 5x 23
411:3x 137
621:3x 3x 3x 23
475:5x 5x 19
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 3x 5x 5x 23 = 10350
Therefore, the value for common factors is 10350.
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 = 14220833242500/(1x10350)
LCM = 14220833242500/10350
LCM = 1373993550
Thus, we can understand that the LCM of 170,690,411,621,475 is 1373993550.
