HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 651, 258, 679 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 651, 258, 679 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 651, 258, 679 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 651, 258, 679 is 1.
HCF(651, 258, 679) = 1
HCF of 651, 258, 679 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 651, 258, 679 is 1.
Highest Common Factor of 651,258,679 is 1
Step 1: Since 651 > 258, we apply the division lemma to 651 and 258, to get
651 = 258 x 2 + 135
Step 2: Since the reminder 258 ≠ 0, we apply division lemma to 135 and 258, to get
258 = 135 x 1 + 123
Step 3: We consider the new divisor 135 and the new remainder 123, and apply the division lemma to get
135 = 123 x 1 + 12
We consider the new divisor 123 and the new remainder 12,and apply the division lemma to get
123 = 12 x 10 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 651 and 258 is 3
Notice that 3 = HCF(12,3) = HCF(123,12) = HCF(135,123) = HCF(258,135) = HCF(651,258) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 679 > 3, we apply the division lemma to 679 and 3, to get
679 = 3 x 226 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 679 is 1
Notice that 1 = HCF(3,1) = HCF(679,3) .
