HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 662, 949 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 662, 949 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 662, 949 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 662, 949 is 1.
HCF(662, 949) = 1
HCF of 662, 949 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 662, 949 is 1.
Highest Common Factor of 662,949 is 1
Step 1: Since 949 > 662, we apply the division lemma to 949 and 662, to get
949 = 662 x 1 + 287
Step 2: Since the reminder 662 ≠ 0, we apply division lemma to 287 and 662, to get
662 = 287 x 2 + 88
Step 3: We consider the new divisor 287 and the new remainder 88, and apply the division lemma to get
287 = 88 x 3 + 23
We consider the new divisor 88 and the new remainder 23,and apply the division lemma to get
88 = 23 x 3 + 19
We consider the new divisor 23 and the new remainder 19,and apply the division lemma to get
23 = 19 x 1 + 4
We consider the new divisor 19 and the new remainder 4,and apply the division lemma to get
19 = 4 x 4 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 662 and 949 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(19,4) = HCF(23,19) = HCF(88,23) = HCF(287,88) = HCF(662,287) = HCF(949,662) .
