HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 675, 391 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 675, 391 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 675, 391 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 675, 391 is 1.
HCF(675, 391) = 1
HCF of 675, 391 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 675, 391 is 1.
Highest Common Factor of 675,391 is 1
Step 1: Since 675 > 391, we apply the division lemma to 675 and 391, to get
675 = 391 x 1 + 284
Step 2: Since the reminder 391 ≠ 0, we apply division lemma to 284 and 391, to get
391 = 284 x 1 + 107
Step 3: We consider the new divisor 284 and the new remainder 107, and apply the division lemma to get
284 = 107 x 2 + 70
We consider the new divisor 107 and the new remainder 70,and apply the division lemma to get
107 = 70 x 1 + 37
We consider the new divisor 70 and the new remainder 37,and apply the division lemma to get
70 = 37 x 1 + 33
We consider the new divisor 37 and the new remainder 33,and apply the division lemma to get
37 = 33 x 1 + 4
We consider the new divisor 33 and the new remainder 4,and apply the division lemma to get
33 = 4 x 8 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 675 and 391 is 1
Notice that 1 = HCF(4,1) = HCF(33,4) = HCF(37,33) = HCF(70,37) = HCF(107,70) = HCF(284,107) = HCF(391,284) = HCF(675,391) .
