HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 553, 2331 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 553, 2331 is 7 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, 2331 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, 2331 is 7.
HCF(553, 2331) = 7
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 553, 2331 is 7.
Step 1: Since 2331 > 553, we apply the division lemma to 2331 and 553, to get
2331 = 553 x 4 + 119
Step 2: Since the reminder 553 ≠ 0, we apply division lemma to 119 and 553, to get
553 = 119 x 4 + 77
Step 3: We consider the new divisor 119 and the new remainder 77, and apply the division lemma to get
119 = 77 x 1 + 42
We consider the new divisor 77 and the new remainder 42,and apply the division lemma to get
77 = 42 x 1 + 35
We consider the new divisor 42 and the new remainder 35,and apply the division lemma to get
42 = 35 x 1 + 7
We consider the new divisor 35 and the new remainder 7,and apply the division lemma to get
35 = 7 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 553 and 2331 is 7
Notice that 7 = HCF(35,7) = HCF(42,35) = HCF(77,42) = HCF(119,77) = HCF(553,119) = HCF(2331,553) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
