Find LCM of 661,572,106,325,440 with Prime Factorization
2 | 661, 572, 106, 325, 440 |
2 | 661, 286, 53, 325, 220 |
5 | 661, 143, 53, 325, 110 |
11 | 661, 143, 53, 65, 22 |
13 | 661, 13, 53, 65, 2 |
661, 1, 53, 5, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 13 x 661 x 1 x 53 x 5 x 2 = 1001943800
Therefore, the lowest common multiple of 661,572,106,325,440 is 1001943800.
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.
661 x 572 x 106 x 325 x 440 = 5731118536000
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.
661 : 1, 661
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
106 : 1, 2, 53, 106
325 : 1, 5, 13, 25, 65, 325
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,572,106,325,440, is 1.
Now, the common factors can be found like this.
661:661
572:2x 2x 11x 13
106:2x 53
325:5x 5x 13
440:2x 2x 2x 5x 11
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 11x 13 = 5720
Therefore, the value for common factors is 5720.
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 = 5731118536000/(1x5720)
LCM = 5731118536000/5720
LCM = 1001943800
Thus, we can understand that the LCM of 661,572,106,325,440 is 1001943800.
