Calculate the LCM of 955,684,931,221

Given numbers are 955,684,931,221

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

The LCM of 955,684,931,221 is 7073719380.

Find LCM of 955,684,931,221 with Prime Factorization


19 955, 684, 931, 221
955, 36, 49, 221

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

19 x 955 x 36 x 49 x 221 = 7073719380

Therefore, the lowest common multiple of 955,684,931,221 is 7073719380.

LCM Formula to Find Lowest Common Multiple of 955,684,931,221

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.

955 x 684 x 931 x 221 = 134400668220

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.

955 : 1, 5, 191, 955

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

931 : 1, 7, 19, 49, 133, 931

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 955,684,931,221, is 1.

Now, the common factors can be found like this.

955:5x 191

684:2x 2x 3x 3x 19

931:7x 7x 19

221:13x 17

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

19 = 19

Therefore, the value for common factors is 19.

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 = 134400668220/(1x19)

LCM = 134400668220/19

LCM = 7073719380

Thus, we can understand that the LCM of 955,684,931,221 is 7073719380.
