Given numbers are 420,507,681,706,632
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,507,681,706,632 is 898656344040.
Find LCM of 420,507,681,706,632 with Prime Factorization
| 2 | 420, 507, 681, 706, 632 |
| 2 | 210, 507, 681, 353, 316 |
| 3 | 105, 507, 681, 353, 158 |
| 35, 169, 227, 353, 158 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 35 x 169 x 227 x 353 x 158 = 898656344040
Therefore, the lowest common multiple of 420,507,681,706,632 is 898656344040.
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.
420 x 507 x 681 x 706 x 632 = 64703256770880
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.
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
507 : 1, 3, 13, 39, 169, 507
681 : 1, 3, 227, 681
706 : 1, 2, 353, 706
632 : 1, 2, 4, 8, 79, 158, 316, 632
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,507,681,706,632, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
507:3x 13x 13
681:3x 227
706:2x 353
632:2x 2x 2x 79
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 64703256770880/(1x72)
LCM = 64703256770880/72
LCM = 898656344040
Thus, we can understand that the LCM of 420,507,681,706,632 is 898656344040.
