Given numbers are 672,869,763,651,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 672,869,763,651,765 is 503173107360.
Find LCM of 672,869,763,651,765 with Prime Factorization
| 3 | 672, 869, 763, 651, 765 |
| 7 | 224, 869, 763, 217, 255 |
| 32, 869, 109, 31, 255 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 32 x 869 x 109 x 31 x 255 = 503173107360
Therefore, the lowest common multiple of 672,869,763,651,765 is 503173107360.
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.
672 x 869 x 763 x 651 x 765 = 221899340345760
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.
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
869 : 1, 11, 79, 869
763 : 1, 7, 109, 763
651 : 1, 3, 7, 21, 31, 93, 217, 651
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,869,763,651,765, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
869:11x 79
763:7x 109
651:3x 7x 31
765:3x 3x 5x 17
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 7x 7 = 441
Therefore, the value for common factors is 441.
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 = 221899340345760/(1x441)
LCM = 221899340345760/441
LCM = 503173107360
Thus, we can understand that the LCM of 672,869,763,651,765 is 503173107360.
