HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 558, 7770, 9694 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 558, 7770, 9694 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 558, 7770, 9694 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 558, 7770, 9694 is 2.
HCF(558, 7770, 9694) = 2
HCF of 558, 7770, 9694 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 558, 7770, 9694 is 2.
Highest Common Factor of 558,7770,9694 is 2
Step 1: Since 7770 > 558, we apply the division lemma to 7770 and 558, to get
7770 = 558 x 13 + 516
Step 2: Since the reminder 558 ≠ 0, we apply division lemma to 516 and 558, to get
558 = 516 x 1 + 42
Step 3: We consider the new divisor 516 and the new remainder 42, and apply the division lemma to get
516 = 42 x 12 + 12
We consider the new divisor 42 and the new remainder 12,and apply the division lemma to get
42 = 12 x 3 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 558 and 7770 is 6
Notice that 6 = HCF(12,6) = HCF(42,12) = HCF(516,42) = HCF(558,516) = HCF(7770,558) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 9694 > 6, we apply the division lemma to 9694 and 6, to get
9694 = 6 x 1615 + 4
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 4 and 6, to get
6 = 4 x 1 + 2
Step 3: 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 6 and 9694 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(9694,6) .
