The LCM of 350,692,641,140,397 is 30817164700.
Find LCM of 350,692,641,140,397 with Prime Factorization
| 2 | 350, 692, 641, 140, 397 |
| 2 | 175, 346, 641, 70, 397 |
| 5 | 175, 173, 641, 35, 397 |
| 7 | 7, 173, 641, 35, 397 |
| 1, 173, 641, 5, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 1 x 173 x 641 x 5 x 397 = 30817164700
Therefore, the lowest common multiple of 350,692,641,140,397 is 30817164700.
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.
350 x 692 x 641 x 140 x 397 = 8628806116000
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.
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
692 : 1, 2, 4, 173, 346, 692
641 : 1, 641
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 350,692,641,140,397, is 1.
Now, the common factors can be found like this.
350:2x 5x 5x 7
692:2x 2x 173
641:641
140:2x 2x 5x 7
397:397
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 2x 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 8628806116000/(1x280)
LCM = 8628806116000/280
LCM = 30817164700
Thus, we can understand that the LCM of 350,692,641,140,397 is 30817164700.
