HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 835, 765, 771, 479 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 835, 765, 771, 479 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 835, 765, 771, 479 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 835, 765, 771, 479 is 1.
HCF(835, 765, 771, 479) = 1
HCF of 835, 765, 771, 479 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 835, 765, 771, 479 is 1.
Highest Common Factor of 835,765,771,479 is 1
Step 1: Since 835 > 765, we apply the division lemma to 835 and 765, to get
835 = 765 x 1 + 70
Step 2: Since the reminder 765 ≠ 0, we apply division lemma to 70 and 765, to get
765 = 70 x 10 + 65
Step 3: We consider the new divisor 70 and the new remainder 65, and apply the division lemma to get
70 = 65 x 1 + 5
We consider the new divisor 65 and the new remainder 5, and apply the division lemma to get
65 = 5 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 835 and 765 is 5
Notice that 5 = HCF(65,5) = HCF(70,65) = HCF(765,70) = HCF(835,765) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 771 > 5, we apply the division lemma to 771 and 5, to get
771 = 5 x 154 + 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 771 is 1
Notice that 1 = HCF(5,1) = HCF(771,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 479 > 1, we apply the division lemma to 479 and 1, to get
479 = 1 x 479 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 479 is 1
Notice that 1 = HCF(479,1) .
