Find LCM of 620,865,948,561,347 with Prime Factorization
| 2 | 620, 865, 948, 561, 347 |
| 2 | 310, 865, 474, 561, 347 |
| 3 | 155, 865, 237, 561, 347 |
| 5 | 155, 865, 79, 187, 347 |
| 31, 173, 79, 187, 347 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 31 x 173 x 79 x 187 x 347 = 1649518611180
Therefore, the lowest common multiple of 620,865,948,561,347 is 1649518611180.
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.
620 x 865 x 948 x 561 x 347 = 98971116670800
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
865 : 1, 5, 173, 865
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
561 : 1, 3, 11, 17, 33, 51, 187, 561
347 : 1, 347
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,865,948,561,347, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
865:5x 173
948:2x 2x 3x 79
561:3x 11x 17
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 5 = 60
Therefore, the value for common factors is 60.
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 = 98971116670800/(1x60)
LCM = 98971116670800/60
LCM = 1649518611180
Thus, we can understand that the LCM of 620,865,948,561,347 is 1649518611180.
