Find LCM of 749,779,646,171,963 with Prime Factorization
3 | 749, 779, 646, 171, 963 |
3 | 749, 779, 646, 57, 321 |
19 | 749, 779, 646, 19, 107 |
107 | 749, 41, 34, 1, 107 |
7, 41, 34, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 19 x 107 x 7 x 41 x 34 x 1 x 1 = 178542126
Therefore, the lowest common multiple of 749,779,646,171,963 is 178542126.
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.
749 x 779 x 646 x 171 x 963 = 62068920309018
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.
749 : 1, 7, 107, 749
779 : 1, 19, 41, 779
646 : 1, 2, 17, 19, 34, 38, 323, 646
171 : 1, 3, 9, 19, 57, 171
963 : 1, 3, 9, 107, 321, 963
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,779,646,171,963, is 1.
Now, the common factors can be found like this.
749:7x 107
779:19x 41
646:2x 17x 19
171:3x 3x 19
963:3x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 19x 19x 107 = 347643
Therefore, the value for common factors is 347643.
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 = 62068920309018/(1x347643)
LCM = 62068920309018/347643
LCM = 178542126
Thus, we can understand that the LCM of 749,779,646,171,963 is 178542126.
