Given numbers are 605,140,142,437

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 605,140,142,437 is 525597380.

Find LCM of 605,140,142,437 with Prime Factorization

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

2 x 5 x 121 x 14 x 71 x 437 = 525597380

Therefore, the lowest common multiple of 605,140,142,437 is 525597380.

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.

605 x 140 x 142 x 437 = 5255973800

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.

605 : 1, 5, 11, 55, 121, 605

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

142 : 1, 2, 71, 142

437 : 1, 19, 23, 437

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,140,142,437, is 1.

Now, the common factors can be found like this.

605:5x 11x 11

140:2x 2x 5x 7

142:2x 71

437:19x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 5255973800/(1x10)

LCM = 5255973800/10

LCM = 525597380

Thus, we can understand that the LCM of 605,140,142,437 is 525597380.
