HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 698, 768, 163 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 698, 768, 163 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 698, 768, 163 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 698, 768, 163 is 1.
HCF(698, 768, 163) = 1
HCF of 698, 768, 163 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 698, 768, 163 is 1.
Highest Common Factor of 698,768,163 is 1
Step 1: Since 768 > 698, we apply the division lemma to 768 and 698, to get
768 = 698 x 1 + 70
Step 2: Since the reminder 698 ≠ 0, we apply division lemma to 70 and 698, to get
698 = 70 x 9 + 68
Step 3: We consider the new divisor 70 and the new remainder 68, and apply the division lemma to get
70 = 68 x 1 + 2
We consider the new divisor 68 and the new remainder 2, and apply the division lemma to get
68 = 2 x 34 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 698 and 768 is 2
Notice that 2 = HCF(68,2) = HCF(70,68) = HCF(698,70) = HCF(768,698) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 163 > 2, we apply the division lemma to 163 and 2, to get
163 = 2 x 81 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 163 is 1
Notice that 1 = HCF(2,1) = HCF(163,2) .
