HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 6418, 697 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 6418, 697 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 6418, 697 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 6418, 697 is 1.
HCF(6418, 697) = 1
HCF of 6418, 697 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 6418, 697 is 1.
Highest Common Factor of 6418,697 is 1
Step 1: Since 6418 > 697, we apply the division lemma to 6418 and 697, to get
6418 = 697 x 9 + 145
Step 2: Since the reminder 697 ≠ 0, we apply division lemma to 145 and 697, to get
697 = 145 x 4 + 117
Step 3: We consider the new divisor 145 and the new remainder 117, and apply the division lemma to get
145 = 117 x 1 + 28
We consider the new divisor 117 and the new remainder 28,and apply the division lemma to get
117 = 28 x 4 + 5
We consider the new divisor 28 and the new remainder 5,and apply the division lemma to get
28 = 5 x 5 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 6418 and 697 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(28,5) = HCF(117,28) = HCF(145,117) = HCF(697,145) = HCF(6418,697) .
