Find LCM of 528,997,791,651,670 with Prime Factorization
| 2 | 528, 997, 791, 651, 670 |
| 3 | 264, 997, 791, 651, 335 |
| 7 | 88, 997, 791, 217, 335 |
| 88, 997, 113, 31, 335 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 88 x 997 x 113 x 31 x 335 = 4324262656560
Therefore, the lowest common multiple of 528,997,791,651,670 is 4324262656560.
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.
528 x 997 x 791 x 651 x 670 = 181619031575520
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.
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
997 : 1, 997
791 : 1, 7, 113, 791
651 : 1, 3, 7, 21, 31, 93, 217, 651
670 : 1, 2, 5, 10, 67, 134, 335, 670
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 528,997,791,651,670, is 1.
Now, the common factors can be found like this.
528:2x 2x 2x 2x 3x 11
997:997
791:7x 113
651:3x 7x 31
670:2x 5x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 181619031575520/(1x42)
LCM = 181619031575520/42
LCM = 4324262656560
Thus, we can understand that the LCM of 528,997,791,651,670 is 4324262656560.
