HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 890, 637 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 890, 637 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 890, 637 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 890, 637 is 1.
HCF(890, 637) = 1
HCF of 890, 637 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 890, 637 is 1.
Highest Common Factor of 890,637 is 1
Step 1: Since 890 > 637, we apply the division lemma to 890 and 637, to get
890 = 637 x 1 + 253
Step 2: Since the reminder 637 ≠ 0, we apply division lemma to 253 and 637, to get
637 = 253 x 2 + 131
Step 3: We consider the new divisor 253 and the new remainder 131, and apply the division lemma to get
253 = 131 x 1 + 122
We consider the new divisor 131 and the new remainder 122,and apply the division lemma to get
131 = 122 x 1 + 9
We consider the new divisor 122 and the new remainder 9,and apply the division lemma to get
122 = 9 x 13 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 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 890 and 637 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(122,9) = HCF(131,122) = HCF(253,131) = HCF(637,253) = HCF(890,637) .
