The LCM, or Least Common Multiple, of 7 and 84 is the smallest multiple that both numbers share. To find the LCM, you can first find the prime factorization of each number: 7 is a prime number, and 84 can be broken down into 2^2 * 3 * 7. To find the LCM, you take the highest power of each prime factor that appears in either number, which in this case would be 2^2 * 3 * 7 = 84. Therefore, the LCM of 7 and 84 is 84.

As a product of its prime factors in exponents: 22*3*7 = 84
To find the greatest common factor (GCF) of 49, 84, and 98, we first need to find the prime factors of each number. The prime factors of 49 are 7 and 7, the prime factors of 84 are 2, 2, 3, and 7, and the prime factors of 98 are 2 and 7. To find the GCF, we look for the common prime factors among the numbers, which are 7. Therefore, the GCF of 49, 84, and 98 is 7.

For 28, 2 and 7. For 84, 2, 3 and 7.
It is: 2^2*3*7 = 84
To find the Highest Common Factor (HCF) of 42, 77, and 84, you first need to find the prime factors of each number. The prime factors of 42 are 2, 3, and 7. The prime factors of 77 are 7 and 11. The prime factors of 84 are 2, 3, and 7. To find the HCF, you need to identify the common prime factors and multiply them together. In this case, the HCF of 42, 77, and 84 is 7.
The LCM, or Least Common Multiple, of 7 and 84 is the smallest multiple that both numbers share.
