The LCM of a group of numbers is the smallest number that all of the given numbers will divide into.The LCM will always be the largest of the given numbers or its multiple. In our case, the largest number is 77. Since 21 and 63 will not divide into 77, the LCM will be a multiple of 77. That multiple will be the number 693 (77 x 9), because: 693/21 = 33 or 21 x 33 = 693; 693/63 = 11 or 63 x 11 = 693. Thus the LCM is 693.
Their product.
9 times 7=63 A simpler answer is 1 times 63!
The product of any two numbers is the answer to the multiplication sum. For example, in the sum 7 x 9 = 63, the number 63 is the product.
The numbers are 62 and 63.
63 = 3 x 3 x 7, so there are more than one combination: 7 & 9 and 21 & 9. That should be it, unless you want to consider the somewhat trivial combinations : 63 & 21, 63 & 9, 63 & 3, 63 & 7.
The LCM of 7 and 9 is 63.
10 and 63
The LCM of 7 and 9 is 63.
The LCM of 7 and 9 is 63.
9 and 21
You don't. You need at least two numbers to find an LCM.
The least common multiple is the smallest number that is multiple of two or more numbers. 21: 21, 42, 63 63: 63 The LCM of 21 and 63 is 63.
Since 63 is a multiple of 9, it is automatically the LCM.
The LCM is: 63
The LCM of 9 and 21 is 63, which is the multiple of the highest power of prime factors from both numbers, is 63. (3² x 7 = 3 x 3 x 7 = 63).
There cannot be a least common multiple if there are not at least two numbers. The least common multiple is the smallest number that is a multiple of the two (or more) numbers. For example, the least common multiple of 4 and 6 is 12. The multiples of 63 are 63, 126, 189, 252, 315, 378, 441, ...
