HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 868, 799, 535, 486 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 868, 799, 535, 486 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 868, 799, 535, 486 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 868, 799, 535, 486 is 1.
HCF(868, 799, 535, 486) = 1
HCF of 868, 799, 535, 486 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 868, 799, 535, 486 is 1.
Highest Common Factor of 868,799,535,486 is 1
Step 1: Since 868 > 799, we apply the division lemma to 868 and 799, to get
868 = 799 x 1 + 69
Step 2: Since the reminder 799 ≠ 0, we apply division lemma to 69 and 799, to get
799 = 69 x 11 + 40
Step 3: We consider the new divisor 69 and the new remainder 40, and apply the division lemma to get
69 = 40 x 1 + 29
We consider the new divisor 40 and the new remainder 29,and apply the division lemma to get
40 = 29 x 1 + 11
We consider the new divisor 29 and the new remainder 11,and apply the division lemma to get
29 = 11 x 2 + 7
We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get
11 = 7 x 1 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 868 and 799 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(29,11) = HCF(40,29) = HCF(69,40) = HCF(799,69) = HCF(868,799) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 535 > 1, we apply the division lemma to 535 and 1, to get
535 = 1 x 535 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 535 is 1
Notice that 1 = HCF(535,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 486 > 1, we apply the division lemma to 486 and 1, to get
486 = 1 x 486 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 486 is 1
Notice that 1 = HCF(486,1) .
