GCF(8, 45, 30) = 1 LCM(8, 45, 30) = 360
Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36.Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.GCF (36, 60, 84) = 12
The GCF is 1. The LCM is 444.
Because 252 is a multiple of 12, 12 and 252 are one pair (252 = 12 x 21 = 252 x 1)Another pair is 36 and 84 (252 = 36 x7 and 84 x 3)252 = 3 x 3 x 4 x 7 = 12 x 3 x 7, so only 36 and 84 are possible multiples of 12.
The LCM is the product of the two numbers divided by their HCF. With 12 and 13, the HCF is 1. Therefore, the LCM will equal the product. With 12 and 14, the HCF is 2. Therefore, the LCM will be half of the product.
The LCM is 420.
84 and 1, respectively.
252
1 and 84, respectively.
Because any smaller positive integer cannot be divided by all the above numbers without remainder. In fact, the presence of 1, when calculating an LCM makes no difference since it will go into any integer. Also, since 12 is a factor of 84, 12 will go into any number that 84 goes into. So the presence of 12 is also irrelevant. Thus, for determining the LCM, only 30 and 84 matter.
84 and 1, respectively.
The Least Common Multiple (LCM) of (12,30) is 60.The lowest common multiple for two numbers can be calculated by:1. Considering the relationship as a ratio.2. Simplifying the ratio (if possible)3. multiplying each original number by the "opposite" ratio.So 12 and 30 are in the ratio of 12 to 30, that is 12:30. This can be simplified to 2:5. You will notice that if we now multiply the 12 by the 5 and the 30 by the 2 we will reach the same answer of 60. 60 is therefore the LCM.
2 x 2 x 3 = 12 2 x 7 = 14 2 x 2 x 3 x 7 = 84, the LCM
The LCF is 1 The GCF is 1. The LCM is 84.
The Least Common Multiple (LCM) for 7 12 is 84.
The LCM is 60.
Since 21 is a factor of 84, it is automatically the GCF. Since 84 is a multiple of 21, it is automatically the LCM.
