Find LCM of 693,735,570,638 with Prime Factorization
| 2 | 693, 735, 570, 638 |
| 3 | 693, 735, 285, 319 |
| 5 | 231, 245, 95, 319 |
| 7 | 231, 49, 19, 319 |
| 11 | 33, 7, 19, 319 |
| 3, 7, 19, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 11 x 3 x 7 x 19 x 29 = 26729010
Therefore, the lowest common multiple of 693,735,570,638 is 26729010.
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.
693 x 735 x 570 x 638 = 185232039300
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,735,570,638, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
735:3x 5x 7x 7
570:2x 3x 5x 19
638:2x 11x 29
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 7x 11 = 6930
Therefore, the value for common factors is 6930.
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 = 185232039300/(1x6930)
LCM = 185232039300/6930
LCM = 26729010
Thus, we can understand that the LCM of 693,735,570,638 is 26729010.
