Find LCM of 735,120,423,640,571 with Prime Factorization
2 | 735, 120, 423, 640, 571 |
2 | 735, 60, 423, 320, 571 |
2 | 735, 30, 423, 160, 571 |
3 | 735, 15, 423, 80, 571 |
5 | 245, 5, 141, 80, 571 |
49, 1, 141, 16, 571 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 49 x 1 x 141 x 16 x 571 = 7574474880
Therefore, the lowest common multiple of 735,120,423,640,571 is 7574474880.
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.
735 x 120 x 423 x 640 x 571 = 13634054784000
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.
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
423 : 1, 3, 9, 47, 141, 423
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
571 : 1, 571
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 735,120,423,640,571, is 1.
Now, the common factors can be found like this.
735:3x 5x 7x 7
120:2x 2x 2x 3x 5
423:3x 3x 47
640:2x 2x 2x 2x 2x 2x 2x 5
571:571
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 3x 3x 5x 5 = 1800
Therefore, the value for common factors is 1800.
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 = 13634054784000/(1x1800)
LCM = 13634054784000/1800
LCM = 7574474880
Thus, we can understand that the LCM of 735,120,423,640,571 is 7574474880.
