HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 556, 694 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 556, 694 is 2 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 556, 694 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 556, 694 is 2.
HCF(556, 694) = 2
HCF of 556, 694 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 556, 694 is 2.
Highest Common Factor of 556,694 is 2
Step 1: Since 694 > 556, we apply the division lemma to 694 and 556, to get
694 = 556 x 1 + 138
Step 2: Since the reminder 556 ≠ 0, we apply division lemma to 138 and 556, to get
556 = 138 x 4 + 4
Step 3: We consider the new divisor 138 and the new remainder 4, and apply the division lemma to get
138 = 4 x 34 + 2
We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 556 and 694 is 2
Notice that 2 = HCF(4,2) = HCF(138,4) = HCF(556,138) = HCF(694,556) .
