HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 727, 927, 844 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 727, 927, 844 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 727, 927, 844 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 727, 927, 844 is 1.
HCF(727, 927, 844) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 727, 927, 844 is 1.
Step 1: Since 927 > 727, we apply the division lemma to 927 and 727, to get
927 = 727 x 1 + 200
Step 2: Since the reminder 727 ≠ 0, we apply division lemma to 200 and 727, to get
727 = 200 x 3 + 127
Step 3: We consider the new divisor 200 and the new remainder 127, and apply the division lemma to get
200 = 127 x 1 + 73
We consider the new divisor 127 and the new remainder 73,and apply the division lemma to get
127 = 73 x 1 + 54
We consider the new divisor 73 and the new remainder 54,and apply the division lemma to get
73 = 54 x 1 + 19
We consider the new divisor 54 and the new remainder 19,and apply the division lemma to get
54 = 19 x 2 + 16
We consider the new divisor 19 and the new remainder 16,and apply the division lemma to get
19 = 16 x 1 + 3
We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get
16 = 3 x 5 + 1
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 727 and 927 is 1
Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(19,16) = HCF(54,19) = HCF(73,54) = HCF(127,73) = HCF(200,127) = HCF(727,200) = HCF(927,727) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 844 > 1, we apply the division lemma to 844 and 1, to get
844 = 1 x 844 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 844 is 1
Notice that 1 = HCF(844,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
