Find LCM of 735,756,780,699,347 with Prime Factorization
| 2 | 735, 756, 780, 699, 347 |
| 2 | 735, 378, 390, 699, 347 |
| 3 | 735, 189, 195, 699, 347 |
| 5 | 245, 63, 65, 233, 347 |
| 7 | 49, 63, 13, 233, 347 |
| 7, 9, 13, 233, 347 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 7 x 9 x 13 x 233 x 347 = 27811126980
Therefore, the lowest common multiple of 735,756,780,699,347 is 27811126980.
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 756 x 780 x 699 x 347 = 105126059984400
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
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
699 : 1, 3, 233, 699
347 : 1, 347
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 735,756,780,699,347, is 1.
Now, the common factors can be found like this.
735:3x 5x 7x 7
756:2x 2x 3x 3x 3x 7
780:2x 2x 3x 5x 13
699:3x 233
347:347
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 3x 3x 3x 5x 7 = 3780
Therefore, the value for common factors is 3780.
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 = 105126059984400/(1x3780)
LCM = 105126059984400/3780
LCM = 27811126980
Thus, we can understand that the LCM of 735,756,780,699,347 is 27811126980.
