HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 247, 825, 51 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 247, 825, 51 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 247, 825, 51 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 247, 825, 51 is 1.
HCF(247, 825, 51) = 1
HCF of 247, 825, 51 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 247, 825, 51 is 1.
Highest Common Factor of 247,825,51 is 1
Step 1: Since 825 > 247, we apply the division lemma to 825 and 247, to get
825 = 247 x 3 + 84
Step 2: Since the reminder 247 ≠ 0, we apply division lemma to 84 and 247, to get
247 = 84 x 2 + 79
Step 3: We consider the new divisor 84 and the new remainder 79, and apply the division lemma to get
84 = 79 x 1 + 5
We consider the new divisor 79 and the new remainder 5,and apply the division lemma to get
79 = 5 x 15 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 247 and 825 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(79,5) = HCF(84,79) = HCF(247,84) = HCF(825,247) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 51 > 1, we apply the division lemma to 51 and 1, to get
51 = 1 x 51 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 51 is 1
Notice that 1 = HCF(51,1) .
