HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 812, 312, 21, 593 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 812, 312, 21, 593 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 812, 312, 21, 593 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 812, 312, 21, 593 is 1.
HCF(812, 312, 21, 593) = 1
HCF of 812, 312, 21, 593 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 812, 312, 21, 593 is 1.
Highest Common Factor of 812,312,21,593 is 1
Step 1: Since 812 > 312, we apply the division lemma to 812 and 312, to get
812 = 312 x 2 + 188
Step 2: Since the reminder 312 ≠ 0, we apply division lemma to 188 and 312, to get
312 = 188 x 1 + 124
Step 3: We consider the new divisor 188 and the new remainder 124, and apply the division lemma to get
188 = 124 x 1 + 64
We consider the new divisor 124 and the new remainder 64,and apply the division lemma to get
124 = 64 x 1 + 60
We consider the new divisor 64 and the new remainder 60,and apply the division lemma to get
64 = 60 x 1 + 4
We consider the new divisor 60 and the new remainder 4,and apply the division lemma to get
60 = 4 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 812 and 312 is 4
Notice that 4 = HCF(60,4) = HCF(64,60) = HCF(124,64) = HCF(188,124) = HCF(312,188) = HCF(812,312) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 21 > 4, we apply the division lemma to 21 and 4, to get
21 = 4 x 5 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 21 is 1
Notice that 1 = HCF(4,1) = HCF(21,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 593 > 1, we apply the division lemma to 593 and 1, to get
593 = 1 x 593 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 593 is 1
Notice that 1 = HCF(593,1) .
