Given numbers are 623,490,254,565,554
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 623,490,254,565,554 is 173359649470.
Find LCM of 623,490,254,565,554 with Prime Factorization
| 2 | 623, 490, 254, 565, 554 |
| 5 | 623, 245, 127, 565, 277 |
| 7 | 623, 49, 127, 113, 277 |
| 89, 7, 127, 113, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 89 x 7 x 127 x 113 x 277 = 173359649470
Therefore, the lowest common multiple of 623,490,254,565,554 is 173359649470.
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.
623 x 490 x 254 x 565 x 554 = 24270350925800
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.
623 : 1, 7, 89, 623
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
254 : 1, 2, 127, 254
565 : 1, 5, 113, 565
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,490,254,565,554, is 1.
Now, the common factors can be found like this.
623:7x 89
490:2x 5x 7x 7
254:2x 127
565:5x 113
554:2x 277
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 7 = 140
Therefore, the value for common factors is 140.
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 = 24270350925800/(1x140)
LCM = 24270350925800/140
LCM = 173359649470
Thus, we can understand that the LCM of 623,490,254,565,554 is 173359649470.
