HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 945, 785, 382 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 945, 785, 382 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 945, 785, 382 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 945, 785, 382 is 1.
HCF(945, 785, 382) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 945, 785, 382 is 1.
Step 1: Since 945 > 785, we apply the division lemma to 945 and 785, to get
945 = 785 x 1 + 160
Step 2: Since the reminder 785 ≠ 0, we apply division lemma to 160 and 785, to get
785 = 160 x 4 + 145
Step 3: We consider the new divisor 160 and the new remainder 145, and apply the division lemma to get
160 = 145 x 1 + 15
We consider the new divisor 145 and the new remainder 15,and apply the division lemma to get
145 = 15 x 9 + 10
We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get
15 = 10 x 1 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 945 and 785 is 5
Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(145,15) = HCF(160,145) = HCF(785,160) = HCF(945,785) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 382 > 5, we apply the division lemma to 382 and 5, to get
382 = 5 x 76 + 2
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get
5 = 2 x 2 + 1
Step 3: 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 5 and 382 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(382,5) .
Here are some samples of HCF using Euclid's Algorithm calculations.
