The LCM is 315.
The LCM of 63 and 84 is 252.
The least common multiple of 63, 105, and 2142 is 10,710.You can determine this by looking at the multiples of each number individually and seeing when they match:63: 63, 126, 189...10,710105: 105, 210, 315...10,7102,142: 2142, 4284, 6426, 8568, 10,710
The LCM is: 63
The LCM is 1155.
The LCM is 315.
The LCM of 63 and 84 is 252.
The LCM is 630 as, 105 x6 =630 63 x 10=630 42x15 = 630
1260
Using digital roots (adding all the digits in a number up until you get a single digit) we can see that: 105: 1+0+5 = 6 63: 6+3 = 9 If both digital roots equal 3,6,and/or 9 then the LCM is always 3. The Normal Way: A few Multiples of 105: 105 / 5 = 21 21 / 7 = 3 3,5,7,21,105 A few Multiples of 63: 63 / 3 = 21 21 / 7 = 3 3,7,21,63 So as you can see, the LCM is 3.
The least common multiple of 63, 105, and 2142 is 10,710.You can determine this by looking at the multiples of each number individually and seeing when they match:63: 63, 126, 189...10,710105: 105, 210, 315...10,7102,142: 2142, 4284, 6426, 8568, 10,710
It is: 630 by finding the prime factors of the given numbers
The LCM (lowest common multiple) for 15 and 21 is 105. 15; 15, 30, 45, 60, 75, 90, 105, 120 21; 21, 42, 63, 84, 105, 126
The LCM is: 63
The LCM is: 105
The LCM is: 105
105 = 3 x 5 x 7; 63 = 3 x 3 x 7. One set of 3 x 7 can be ignored so LCM = 3 x 5 x 7 x 3 ie 315315
