HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 99, 25, 27, 285 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 99, 25, 27, 285 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 99, 25, 27, 285 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 99, 25, 27, 285 is 1.
HCF(99, 25, 27, 285) = 1
HCF of 99, 25, 27, 285 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 99, 25, 27, 285 is 1.
Highest Common Factor of 99,25,27,285 is 1
Step 1: Since 99 > 25, we apply the division lemma to 99 and 25, to get
99 = 25 x 3 + 24
Step 2: Since the reminder 25 ≠ 0, we apply division lemma to 24 and 25, to get
25 = 24 x 1 + 1
Step 3: We consider the new divisor 24 and the new remainder 1, and apply the division lemma to get
24 = 1 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 99 and 25 is 1
Notice that 1 = HCF(24,1) = HCF(25,24) = HCF(99,25) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 27 > 1, we apply the division lemma to 27 and 1, to get
27 = 1 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 27 is 1
Notice that 1 = HCF(27,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 285 > 1, we apply the division lemma to 285 and 1, to get
285 = 1 x 285 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 285 is 1
Notice that 1 = HCF(285,1) .
