HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 667, 389, 298 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 667, 389, 298 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 667, 389, 298 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 667, 389, 298 is 1.
HCF(667, 389, 298) = 1
HCF of 667, 389, 298 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 667, 389, 298 is 1.
Highest Common Factor of 667,389,298 is 1
Step 1: Since 667 > 389, we apply the division lemma to 667 and 389, to get
667 = 389 x 1 + 278
Step 2: Since the reminder 389 ≠ 0, we apply division lemma to 278 and 389, to get
389 = 278 x 1 + 111
Step 3: We consider the new divisor 278 and the new remainder 111, and apply the division lemma to get
278 = 111 x 2 + 56
We consider the new divisor 111 and the new remainder 56,and apply the division lemma to get
111 = 56 x 1 + 55
We consider the new divisor 56 and the new remainder 55,and apply the division lemma to get
56 = 55 x 1 + 1
We consider the new divisor 55 and the new remainder 1,and apply the division lemma to get
55 = 1 x 55 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 667 and 389 is 1
Notice that 1 = HCF(55,1) = HCF(56,55) = HCF(111,56) = HCF(278,111) = HCF(389,278) = HCF(667,389) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 298 > 1, we apply the division lemma to 298 and 1, to get
298 = 1 x 298 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 298 is 1
Notice that 1 = HCF(298,1) .
