Given numbers are 421,621,761,672,759
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,621,761,672,759 is 490229064864.
Find LCM of 421,621,761,672,759 with Prime Factorization
| 3 | 421, 621, 761, 672, 759 |
| 23 | 421, 207, 761, 224, 253 |
| 421, 9, 761, 224, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 421 x 9 x 761 x 224 x 11 = 490229064864
Therefore, the lowest common multiple of 421,621,761,672,759 is 490229064864.
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 621 x 761 x 672 x 759 = 101477416426848
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
621 : 1, 3, 9, 23, 27, 69, 207, 621
761 : 1, 761
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
759 : 1, 3, 11, 23, 33, 69, 253, 759
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,621,761,672,759, is 1.
Now, the common factors can be found like this.
421:421
621:3x 3x 3x 23
761:761
672:2x 2x 2x 2x 2x 3x 7
759:3x 11x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 23 = 207
Therefore, the value for common factors is 207.
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 = 101477416426848/(1x207)
LCM = 101477416426848/207
LCM = 490229064864
Thus, we can understand that the LCM of 421,621,761,672,759 is 490229064864.
