HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 572, 812, 127 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 572, 812, 127 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 572, 812, 127 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 572, 812, 127 is 1.
HCF(572, 812, 127) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 572, 812, 127 is 1.
Step 1: Since 812 > 572, we apply the division lemma to 812 and 572, to get
812 = 572 x 1 + 240
Step 2: Since the reminder 572 ≠ 0, we apply division lemma to 240 and 572, to get
572 = 240 x 2 + 92
Step 3: We consider the new divisor 240 and the new remainder 92, and apply the division lemma to get
240 = 92 x 2 + 56
We consider the new divisor 92 and the new remainder 56,and apply the division lemma to get
92 = 56 x 1 + 36
We consider the new divisor 56 and the new remainder 36,and apply the division lemma to get
56 = 36 x 1 + 20
We consider the new divisor 36 and the new remainder 20,and apply the division lemma to get
36 = 20 x 1 + 16
We consider the new divisor 20 and the new remainder 16,and apply the division lemma to get
20 = 16 x 1 + 4
We consider the new divisor 16 and the new remainder 4,and apply the division lemma to get
16 = 4 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 572 and 812 is 4
Notice that 4 = HCF(16,4) = HCF(20,16) = HCF(36,20) = HCF(56,36) = HCF(92,56) = HCF(240,92) = HCF(572,240) = HCF(812,572) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 127 > 4, we apply the division lemma to 127 and 4, to get
127 = 4 x 31 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma 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 4 and 127 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(127,4) .
Here are some samples of HCF using Euclid's Algorithm calculations.
