HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 553, 1963 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 553, 1963 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 553, 1963 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 553, 1963 is 1.
HCF(553, 1963) = 1
HCF of 553, 1963 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 553, 1963 is 1.
Highest Common Factor of 553,1963 is 1
Step 1: Since 1963 > 553, we apply the division lemma to 1963 and 553, to get
1963 = 553 x 3 + 304
Step 2: Since the reminder 553 ≠ 0, we apply division lemma to 304 and 553, to get
553 = 304 x 1 + 249
Step 3: We consider the new divisor 304 and the new remainder 249, and apply the division lemma to get
304 = 249 x 1 + 55
We consider the new divisor 249 and the new remainder 55,and apply the division lemma to get
249 = 55 x 4 + 29
We consider the new divisor 55 and the new remainder 29,and apply the division lemma to get
55 = 29 x 1 + 26
We consider the new divisor 29 and the new remainder 26,and apply the division lemma to get
29 = 26 x 1 + 3
We consider the new divisor 26 and the new remainder 3,and apply the division lemma to get
26 = 3 x 8 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
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 553 and 1963 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(26,3) = HCF(29,26) = HCF(55,29) = HCF(249,55) = HCF(304,249) = HCF(553,304) = HCF(1963,553) .
