7 29, 53, 7, 91, 101
29, 53, 1, 13, 101

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 2 x 3 x 5 x 7 x 29 x 53 x 1 x 13 x 101 = 1695188040

Therefore, the lowest common multiple of 145,424,840,546,808 is 1695188040.

LCM Formula to Find Lowest Common Multiple of 145,424,840,546,808

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.

145 x 424 x 840 x 546 x 808 = 22783327257600

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.

145 : 1, 5, 29, 145

424 : 1, 2, 4, 8, 53, 106, 212, 424

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

808 : 1, 2, 4, 8, 101, 202, 404, 808

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 145,424,840,546,808, is 1.

Now, the common factors can be found like this.

145:5x 29

424:2x 2x 2x 53

840:2x 2x 2x 3x 5x 7

546:2x 3x 7x 13

808:2x 2x 2x 101

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 3x 5x 7 = 13440

Therefore, the value for common factors is 13440.

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 = 22783327257600/(1x13440)

LCM = 22783327257600/13440

LCM = 1695188040

Thus, we can understand that the LCM of 145,424,840,546,808 is 1695188040.
