Find LCM of 546,931,672,689 with Prime Factorization
| 2 | 546, 931, 672, 689 |
| 3 | 273, 931, 336, 689 |
| 7 | 91, 931, 112, 689 |
| 13 | 13, 133, 16, 689 |
| 1, 133, 16, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 1 x 133 x 16 x 53 = 61580064
Therefore, the lowest common multiple of 546,931,672,689 is 61580064.
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.
546 x 931 x 672 x 689 = 235359004608
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.
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
931 : 1, 7, 19, 49, 133, 931
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
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,931,672,689, is 1.
Now, the common factors can be found like this.
546:2x 3x 7x 13
931:7x 7x 19
672:2x 2x 2x 2x 2x 3x 7
689:13x 53
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 7x 7x 13 = 3822
Therefore, the value for common factors is 3822.
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 = 235359004608/(1x3822)
LCM = 235359004608/3822
LCM = 61580064
Thus, we can understand that the LCM of 546,931,672,689 is 61580064.
