HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 830, 665, 351 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 830, 665, 351 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 830, 665, 351 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 830, 665, 351 is 1.
HCF(830, 665, 351) = 1
HCF of 830, 665, 351 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 830, 665, 351 is 1.
Highest Common Factor of 830,665,351 is 1
Step 1: Since 830 > 665, we apply the division lemma to 830 and 665, to get
830 = 665 x 1 + 165
Step 2: Since the reminder 665 ≠ 0, we apply division lemma to 165 and 665, to get
665 = 165 x 4 + 5
Step 3: We consider the new divisor 165 and the new remainder 5, and apply the division lemma to get
165 = 5 x 33 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 830 and 665 is 5
Notice that 5 = HCF(165,5) = HCF(665,165) = HCF(830,665) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 351 > 5, we apply the division lemma to 351 and 5, to get
351 = 5 x 70 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 351 is 1
Notice that 1 = HCF(5,1) = HCF(351,5) .
