Find LCM of 646,497,140,893,841 with Prime Factorization
2 | 646, 497, 140, 893, 841 |
7 | 323, 497, 70, 893, 841 |
19 | 323, 71, 10, 893, 841 |
17, 71, 10, 47, 841 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 17 x 71 x 10 x 47 x 841 = 126906176740
Therefore, the lowest common multiple of 646,497,140,893,841 is 126906176740.
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.
646 x 497 x 140 x 893 x 841 = 33757043012840
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
497 : 1, 7, 71, 497
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
893 : 1, 19, 47, 893
841 : 1, 29, 841
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,497,140,893,841, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
497:7x 71
140:2x 2x 5x 7
893:19x 47
841:29x 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 7x 19 = 266
Therefore, the value for common factors is 266.
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 = 33757043012840/(1x266)
LCM = 33757043012840/266
LCM = 126906176740
Thus, we can understand that the LCM of 646,497,140,893,841 is 126906176740.
