Find LCM of 724,672,389,640,458 with Prime Factorization
2 | 724, 672, 389, 640, 458 |
2 | 362, 336, 389, 320, 229 |
2 | 181, 168, 389, 160, 229 |
2 | 181, 84, 389, 80, 229 |
2 | 181, 42, 389, 40, 229 |
181, 21, 389, 20, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 181 x 21 x 389 x 20 x 229 = 216702003840
Therefore, the lowest common multiple of 724,672,389,640,458 is 216702003840.
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.
724 x 672 x 389 x 640 x 458 = 55475712983040
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.
724 : 1, 2, 4, 181, 362, 724
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
389 : 1, 389
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
458 : 1, 2, 229, 458
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,672,389,640,458, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
672:2x 2x 2x 2x 2x 3x 7
389:389
640:2x 2x 2x 2x 2x 2x 2x 5
458:2x 229
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 2x 2x 2x 2x 2 = 256
Therefore, the value for common factors is 256.
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 = 55475712983040/(1x256)
LCM = 55475712983040/256
LCM = 216702003840
Thus, we can understand that the LCM of 724,672,389,640,458 is 216702003840.
