The number could be either 14 or 16.
The Least Common Multiple (LCM) for7 20is140
4
The GCF is 4.
The GCF is 4.
The highest common factor is: 20
The common factors of 16 and 20 are 1, 2, and 4. The greatest or highest common factor is the highest number that divides exactly into two or more numbers. 16: 1, 2, 4, 8, 16 20: 1, 2, 4, 5, 10, 20 The greatest common factor for 16 and 20 is 4. --- To find using primes: 16 = 2 x 2 x 2 x 2 20 = 2 x 2 x 5 Common primes (2, 2) and 2 x 2 = 4
Yes. 3 and 20
The highest common factor 16 and 20 is 4.So divide both the numerator and the denominator of the ratio, 16/20 by this HCF. The answer, therefore is 4/5.
The highest common factor of 12 and 20 is 4.
The LCM of 20 and 16 is 80, which is the multiple of the highest power of prime factors from both numbers (20 = 22 x 5 and 16 = 24; LCM of 20 and 16 is 24 x 5 = 16 x 5 = 80).
