HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 973, 637, 422 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 973, 637, 422 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 973, 637, 422 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 973, 637, 422 is 1.
HCF(973, 637, 422) = 1
HCF of 973, 637, 422 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 973, 637, 422 is 1.
Highest Common Factor of 973,637,422 is 1
Step 1: Since 973 > 637, we apply the division lemma to 973 and 637, to get
973 = 637 x 1 + 336
Step 2: Since the reminder 637 ≠ 0, we apply division lemma to 336 and 637, to get
637 = 336 x 1 + 301
Step 3: We consider the new divisor 336 and the new remainder 301, and apply the division lemma to get
336 = 301 x 1 + 35
We consider the new divisor 301 and the new remainder 35,and apply the division lemma to get
301 = 35 x 8 + 21
We consider the new divisor 35 and the new remainder 21,and apply the division lemma to get
35 = 21 x 1 + 14
We consider the new divisor 21 and the new remainder 14,and apply the division lemma to get
21 = 14 x 1 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 973 and 637 is 7
Notice that 7 = HCF(14,7) = HCF(21,14) = HCF(35,21) = HCF(301,35) = HCF(336,301) = HCF(637,336) = HCF(973,637) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 422 > 7, we apply the division lemma to 422 and 7, to get
422 = 7 x 60 + 2
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 2 and 7, to get
7 = 2 x 3 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 422 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(422,7) .
