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

2 x 2 x 3 x 5 x 7 x 71 x 2 x 31 x 211 = 390105240

Therefore, the lowest common multiple of 355,840,868,633 is 390105240.

LCM Formula to Find Lowest Common Multiple of 355,840,868,633

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.

355 x 840 x 868 x 633 = 163844200800

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.

355 : 1, 5, 71, 355

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

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

633 : 1, 3, 211, 633

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,840,868,633, is 1.

Now, the common factors can be found like this.

355:5x 71

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

868:2x 2x 7x 31

633:3x 211

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 3x 5x 7 = 420

Therefore, the value for common factors is 420.

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 = 163844200800/(1x420)

LCM = 163844200800/420

LCM = 390105240

Thus, we can understand that the LCM of 355,840,868,633 is 390105240.
