HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 943, 746, 433 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 943, 746, 433 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, 746, 433 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, 746, 433 is 1.
HCF(943, 746, 433) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 943, 746, 433 is 1.
Step 1: Since 943 > 746, we apply the division lemma to 943 and 746, to get
943 = 746 x 1 + 197
Step 2: Since the reminder 746 ≠ 0, we apply division lemma to 197 and 746, to get
746 = 197 x 3 + 155
Step 3: We consider the new divisor 197 and the new remainder 155, and apply the division lemma to get
197 = 155 x 1 + 42
We consider the new divisor 155 and the new remainder 42,and apply the division lemma to get
155 = 42 x 3 + 29
We consider the new divisor 42 and the new remainder 29,and apply the division lemma to get
42 = 29 x 1 + 13
We consider the new divisor 29 and the new remainder 13,and apply the division lemma to get
29 = 13 x 2 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 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 943 and 746 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(29,13) = HCF(42,29) = HCF(155,42) = HCF(197,155) = HCF(746,197) = HCF(943,746) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 433 > 1, we apply the division lemma to 433 and 1, to get
433 = 1 x 433 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 433 is 1
Notice that 1 = HCF(433,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
