Given numbers are 905,253,190,428

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

The LCM of 905,253,190,428 is 1861943380.

Find LCM of 905,253,190,428 with Prime Factorization

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

2 x 5 x 181 x 253 x 19 x 214 = 1861943380

Therefore, the lowest common multiple of 905,253,190,428 is 1861943380.

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.

905 x 253 x 190 x 428 = 18619433800

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.

905 : 1, 5, 181, 905

253 : 1, 11, 23, 253

190 : 1, 2, 5, 10, 19, 38, 95, 190

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,253,190,428, is 1.

Now, the common factors can be found like this.

905:5x 181

253:11x 23

190:2x 5x 19

428:2x 2x 107

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 = 18619433800/(1x10)

LCM = 18619433800/10

LCM = 1861943380

Thus, we can understand that the LCM of 905,253,190,428 is 1861943380.
