The LCM of 421,716,506,176,993 is 302917859376.
Find LCM of 421,716,506,176,993 with Prime Factorization
| 2 | 421, 716, 506, 176, 993 |
| 2 | 421, 358, 253, 88, 993 |
| 11 | 421, 179, 253, 44, 993 |
| 421, 179, 23, 4, 993 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 421 x 179 x 23 x 4 x 993 = 302917859376
Therefore, the lowest common multiple of 421,716,506,176,993 is 302917859376.
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.
421 x 716 x 506 x 176 x 993 = 26656771625088
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.
421 : 1, 421
716 : 1, 2, 4, 179, 358, 716
506 : 1, 2, 11, 22, 23, 46, 253, 506
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,716,506,176,993, is 1.
Now, the common factors can be found like this.
421:421
716:2x 2x 179
506:2x 11x 23
176:2x 2x 2x 2x 11
993:3x 331
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 11 = 88
Therefore, the value for common factors is 88.
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 = 26656771625088/(1x88)
LCM = 26656771625088/88
LCM = 302917859376
Thus, we can understand that the LCM of 421,716,506,176,993 is 302917859376.
