Find LCM of 981,736,515,735,770 with Prime Factorization
2 | 981, 736, 515, 735, 770 |
3 | 981, 368, 515, 735, 385 |
5 | 327, 368, 515, 245, 385 |
7 | 327, 368, 103, 49, 77 |
327, 368, 103, 7, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 327 x 368 x 103 x 7 x 11 = 200420811360
Therefore, the lowest common multiple of 981,736,515,735,770 is 200420811360.
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.
981 x 736 x 515 x 735 x 770 = 210441851928000
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.
981 : 1, 3, 9, 109, 327, 981
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
515 : 1, 5, 103, 515
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,736,515,735,770, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
736:2x 2x 2x 2x 2x 23
515:5x 103
735:3x 5x 7x 7
770:2x 5x 7x 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 3x 5x 5x 7 = 1050
Therefore, the value for common factors is 1050.
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 = 210441851928000/(1x1050)
LCM = 210441851928000/1050
LCM = 200420811360
Thus, we can understand that the LCM of 981,736,515,735,770 is 200420811360.
