HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 689, 556 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 689, 556 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 689, 556 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 689, 556 is 1.
HCF(689, 556) = 1
HCF of 689, 556 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 689, 556 is 1.
Highest Common Factor of 689,556 is 1
Step 1: Since 689 > 556, we apply the division lemma to 689 and 556, to get
689 = 556 x 1 + 133
Step 2: Since the reminder 556 ≠ 0, we apply division lemma to 133 and 556, to get
556 = 133 x 4 + 24
Step 3: We consider the new divisor 133 and the new remainder 24, and apply the division lemma to get
133 = 24 x 5 + 13
We consider the new divisor 24 and the new remainder 13,and apply the division lemma to get
24 = 13 x 1 + 11
We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get
13 = 11 x 1 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 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 689 and 556 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(24,13) = HCF(133,24) = HCF(556,133) = HCF(689,556) .
