HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 943, 804, 340 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 943, 804, 340 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 943, 804, 340 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 943, 804, 340 is 1.
HCF(943, 804, 340) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 943, 804, 340 is 1.
Step 1: Since 943 > 804, we apply the division lemma to 943 and 804, to get
943 = 804 x 1 + 139
Step 2: Since the reminder 804 ≠ 0, we apply division lemma to 139 and 804, to get
804 = 139 x 5 + 109
Step 3: We consider the new divisor 139 and the new remainder 109, and apply the division lemma to get
139 = 109 x 1 + 30
We consider the new divisor 109 and the new remainder 30,and apply the division lemma to get
109 = 30 x 3 + 19
We consider the new divisor 30 and the new remainder 19,and apply the division lemma to get
30 = 19 x 1 + 11
We consider the new divisor 19 and the new remainder 11,and apply the division lemma to get
19 = 11 x 1 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 943 and 804 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(19,11) = HCF(30,19) = HCF(109,30) = HCF(139,109) = HCF(804,139) = HCF(943,804) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 340 > 1, we apply the division lemma to 340 and 1, to get
340 = 1 x 340 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 340 is 1
Notice that 1 = HCF(340,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
