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

2 x 2 x 2 x 3 x 5 x 7 x 251 x 131 x 47 x 1 x 1 = 1298141880

Therefore, the lowest common multiple of 753,655,987,840,168 is 1298141880.

LCM Formula to Find Lowest Common Multiple of 753,655,987,840,168

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.

753 x 655 x 987 x 840 x 168 = 68697668289600

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.

753 : 1, 3, 251, 753

655 : 1, 5, 131, 655

987 : 1, 3, 7, 21, 47, 141, 329, 987

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

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 753,655,987,840,168, is 1.

Now, the common factors can be found like this.

753:3x 251

655:5x 131

987:3x 7x 47

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

168:2x 2x 2x 3x 7

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 3x 3x 3x 5x 7x 7 = 52920

Therefore, the value for common factors is 52920.

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 = 68697668289600/(1x52920)

LCM = 68697668289600/52920

LCM = 1298141880

Thus, we can understand that the LCM of 753,655,987,840,168 is 1298141880.
