Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 x 17 x 143 x 2 x 7 x 17 x 5 = 1110869760
Therefore, the lowest common multiple of 429,768,714,289,640 is 1110869760.
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.
429 x 768 x 714 x 289 x 640 = 43510546759680
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.
429 : 1, 3, 11, 13, 33, 39, 143, 429
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
289 : 1, 17, 289
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,768,714,289,640, is 1.
Now, the common factors can be found like this.
429:3x 11x 13
768:2x 2x 2x 2x 2x 2x 2x 2x 3
714:2x 3x 7x 17
289:17x 17
640:2x 2x 2x 2x 2x 2x 2x 5
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 2x 3x 3x 17 = 39168
Therefore, the value for common factors is 39168.
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 = 43510546759680/(1x39168)
LCM = 43510546759680/39168
LCM = 1110869760
Thus, we can understand that the LCM of 429,768,714,289,640 is 1110869760.
