HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 211, 969, 431 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 211, 969, 431 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 211, 969, 431 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 211, 969, 431 is 1.
HCF(211, 969, 431) = 1
HCF of 211, 969, 431 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 211, 969, 431 is 1.
Highest Common Factor of 211,969,431 is 1
Step 1: Since 969 > 211, we apply the division lemma to 969 and 211, to get
969 = 211 x 4 + 125
Step 2: Since the reminder 211 ≠ 0, we apply division lemma to 125 and 211, to get
211 = 125 x 1 + 86
Step 3: We consider the new divisor 125 and the new remainder 86, and apply the division lemma to get
125 = 86 x 1 + 39
We consider the new divisor 86 and the new remainder 39,and apply the division lemma to get
86 = 39 x 2 + 8
We consider the new divisor 39 and the new remainder 8,and apply the division lemma to get
39 = 8 x 4 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 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 211 and 969 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(39,8) = HCF(86,39) = HCF(125,86) = HCF(211,125) = HCF(969,211) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 431 > 1, we apply the division lemma to 431 and 1, to get
431 = 1 x 431 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 431 is 1
Notice that 1 = HCF(431,1) .
