HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 64, 40, 86, 829 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 64, 40, 86, 829 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 64, 40, 86, 829 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 64, 40, 86, 829 is 1.
HCF(64, 40, 86, 829) = 1
HCF of 64, 40, 86, 829 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 64, 40, 86, 829 is 1.
Highest Common Factor of 64,40,86,829 is 1
Step 1: Since 64 > 40, we apply the division lemma to 64 and 40, to get
64 = 40 x 1 + 24
Step 2: Since the reminder 40 ≠ 0, we apply division lemma to 24 and 40, to get
40 = 24 x 1 + 16
Step 3: We consider the new divisor 24 and the new remainder 16, and apply the division lemma to get
24 = 16 x 1 + 8
We consider the new divisor 16 and the new remainder 8, and apply the division lemma to get
16 = 8 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 64 and 40 is 8
Notice that 8 = HCF(16,8) = HCF(24,16) = HCF(40,24) = HCF(64,40) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 86 > 8, we apply the division lemma to 86 and 8, to get
86 = 8 x 10 + 6
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 6 and 8, to get
8 = 6 x 1 + 2
Step 3: We consider the new divisor 6 and the new remainder 2, and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 8 and 86 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(86,8) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 829 > 2, we apply the division lemma to 829 and 2, to get
829 = 2 x 414 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 829 is 1
Notice that 1 = HCF(2,1) = HCF(829,2) .
