HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 827, 221, 973 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 827, 221, 973 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 827, 221, 973 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 827, 221, 973 is 1.
HCF(827, 221, 973) = 1
HCF of 827, 221, 973 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 827, 221, 973 is 1.
Highest Common Factor of 827,221,973 is 1
Step 1: Since 827 > 221, we apply the division lemma to 827 and 221, to get
827 = 221 x 3 + 164
Step 2: Since the reminder 221 ≠ 0, we apply division lemma to 164 and 221, to get
221 = 164 x 1 + 57
Step 3: We consider the new divisor 164 and the new remainder 57, and apply the division lemma to get
164 = 57 x 2 + 50
We consider the new divisor 57 and the new remainder 50,and apply the division lemma to get
57 = 50 x 1 + 7
We consider the new divisor 50 and the new remainder 7,and apply the division lemma to get
50 = 7 x 7 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 827 and 221 is 1
Notice that 1 = HCF(7,1) = HCF(50,7) = HCF(57,50) = HCF(164,57) = HCF(221,164) = HCF(827,221) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 973 > 1, we apply the division lemma to 973 and 1, to get
973 = 1 x 973 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 973 is 1
Notice that 1 = HCF(973,1) .
