HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 211, 568, 21, 728 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 211, 568, 21, 728 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 211, 568, 21, 728 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 211, 568, 21, 728 is 1.
HCF(211, 568, 21, 728) = 1
HCF of 211, 568, 21, 728 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 211, 568, 21, 728 is 1.
Highest Common Factor of 211,568,21,728 is 1
Step 1: Since 568 > 211, we apply the division lemma to 568 and 211, to get
568 = 211 x 2 + 146
Step 2: Since the reminder 211 ≠ 0, we apply division lemma to 146 and 211, to get
211 = 146 x 1 + 65
Step 3: We consider the new divisor 146 and the new remainder 65, and apply the division lemma to get
146 = 65 x 2 + 16
We consider the new divisor 65 and the new remainder 16,and apply the division lemma to get
65 = 16 x 4 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 211 and 568 is 1
Notice that 1 = HCF(16,1) = HCF(65,16) = HCF(146,65) = HCF(211,146) = HCF(568,211) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 21 > 1, we apply the division lemma to 21 and 1, to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 21 is 1
Notice that 1 = HCF(21,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 728 > 1, we apply the division lemma to 728 and 1, to get
728 = 1 x 728 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 728 is 1
Notice that 1 = HCF(728,1) .
