HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 698, 67946 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 698, 67946 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 698, 67946 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, 67946 is 2.
HCF(698, 67946) = 2
HCF of 698, 67946 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, 67946 is 2.
Highest Common Factor of 698,67946 is 2
Step 1: Since 67946 > 698, we apply the division lemma to 67946 and 698, to get
67946 = 698 x 97 + 240
Step 2: Since the reminder 698 ≠ 0, we apply division lemma to 240 and 698, to get
698 = 240 x 2 + 218
Step 3: We consider the new divisor 240 and the new remainder 218, and apply the division lemma to get
240 = 218 x 1 + 22
We consider the new divisor 218 and the new remainder 22,and apply the division lemma to get
218 = 22 x 9 + 20
We consider the new divisor 22 and the new remainder 20,and apply the division lemma to get
22 = 20 x 1 + 2
We consider the new divisor 20 and the new remainder 2,and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 698 and 67946 is 2
Notice that 2 = HCF(20,2) = HCF(22,20) = HCF(218,22) = HCF(240,218) = HCF(698,240) = HCF(67946,698) .
