HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 501, 684, 28, 646 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 501, 684, 28, 646 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 501, 684, 28, 646 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 501, 684, 28, 646 is 1.
HCF(501, 684, 28, 646) = 1
HCF of 501, 684, 28, 646 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 501, 684, 28, 646 is 1.
Highest Common Factor of 501,684,28,646 is 1
Step 1: Since 684 > 501, we apply the division lemma to 684 and 501, to get
684 = 501 x 1 + 183
Step 2: Since the reminder 501 ≠ 0, we apply division lemma to 183 and 501, to get
501 = 183 x 2 + 135
Step 3: We consider the new divisor 183 and the new remainder 135, and apply the division lemma to get
183 = 135 x 1 + 48
We consider the new divisor 135 and the new remainder 48,and apply the division lemma to get
135 = 48 x 2 + 39
We consider the new divisor 48 and the new remainder 39,and apply the division lemma to get
48 = 39 x 1 + 9
We consider the new divisor 39 and the new remainder 9,and apply the division lemma to get
39 = 9 x 4 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 501 and 684 is 3
Notice that 3 = HCF(9,3) = HCF(39,9) = HCF(48,39) = HCF(135,48) = HCF(183,135) = HCF(501,183) = HCF(684,501) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 28 > 3, we apply the division lemma to 28 and 3, to get
28 = 3 x 9 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 28 is 1
Notice that 1 = HCF(3,1) = HCF(28,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 646 > 1, we apply the division lemma to 646 and 1, to get
646 = 1 x 646 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 646 is 1
Notice that 1 = HCF(646,1) .
