HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 621, 821, 272, 98 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 621, 821, 272, 98 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 621, 821, 272, 98 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 621, 821, 272, 98 is 1.
HCF(621, 821, 272, 98) = 1
HCF of 621, 821, 272, 98 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 621, 821, 272, 98 is 1.
Highest Common Factor of 621,821,272,98 is 1
Step 1: Since 821 > 621, we apply the division lemma to 821 and 621, to get
821 = 621 x 1 + 200
Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 200 and 621, to get
621 = 200 x 3 + 21
Step 3: We consider the new divisor 200 and the new remainder 21, and apply the division lemma to get
200 = 21 x 9 + 11
We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get
21 = 11 x 1 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 621 and 821 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(200,21) = HCF(621,200) = HCF(821,621) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 272 > 1, we apply the division lemma to 272 and 1, to get
272 = 1 x 272 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 272 is 1
Notice that 1 = HCF(272,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 98 > 1, we apply the division lemma to 98 and 1, to get
98 = 1 x 98 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 98 is 1
Notice that 1 = HCF(98,1) .
