HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 826, 584, 621, 65 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 826, 584, 621, 65 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 826, 584, 621, 65 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 826, 584, 621, 65 is 1.
HCF(826, 584, 621, 65) = 1
HCF of 826, 584, 621, 65 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 826, 584, 621, 65 is 1.
Highest Common Factor of 826,584,621,65 is 1
Step 1: Since 826 > 584, we apply the division lemma to 826 and 584, to get
826 = 584 x 1 + 242
Step 2: Since the reminder 584 ≠ 0, we apply division lemma to 242 and 584, to get
584 = 242 x 2 + 100
Step 3: We consider the new divisor 242 and the new remainder 100, and apply the division lemma to get
242 = 100 x 2 + 42
We consider the new divisor 100 and the new remainder 42,and apply the division lemma to get
100 = 42 x 2 + 16
We consider the new divisor 42 and the new remainder 16,and apply the division lemma to get
42 = 16 x 2 + 10
We consider the new divisor 16 and the new remainder 10,and apply the division lemma to get
16 = 10 x 1 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 826 and 584 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(16,10) = HCF(42,16) = HCF(100,42) = HCF(242,100) = HCF(584,242) = HCF(826,584) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 621 > 2, we apply the division lemma to 621 and 2, to get
621 = 2 x 310 + 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 621 is 1
Notice that 1 = HCF(2,1) = HCF(621,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 65 > 1, we apply the division lemma to 65 and 1, to get
65 = 1 x 65 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 65 is 1
Notice that 1 = HCF(65,1) .
