Find LCM of 724,546,142,871,813 with Prime Factorization


2 724, 546, 142, 871, 813
3 362, 273, 71, 871, 813
13 362, 91, 71, 871, 271
362, 7, 71, 67, 271

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

2 x 3 x 13 x 362 x 7 x 71 x 67 x 271 = 254802482844

Therefore, the lowest common multiple of 724,546,142,871,813 is 254802482844.

LCM Formula to Find Lowest Common Multiple of 724,546,142,871,813

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.

724 x 546 x 142 x 871 x 813 = 39749187323664

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.

724 : 1, 2, 4, 181, 362, 724

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

142 : 1, 2, 71, 142

871 : 1, 13, 67, 871

813 : 1, 3, 271, 813

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,546,142,871,813, is 1.

Now, the common factors can be found like this.

724:2x 2x 181

546:2x 3x 7x 13

142:2x 71

871:13x 67

813:3x 271

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 13 = 156

Therefore, the value for common factors is 156.

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 = 39749187323664/(1x156)

LCM = 39749187323664/156

LCM = 254802482844

Thus, we can understand that the LCM of 724,546,142,871,813 is 254802482844.
