HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 786, 478, 375 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 786, 478, 375 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 786, 478, 375 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 786, 478, 375 is 1.
HCF(786, 478, 375) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 786, 478, 375 is 1.
Step 1: Since 786 > 478, we apply the division lemma to 786 and 478, to get
786 = 478 x 1 + 308
Step 2: Since the reminder 478 ≠ 0, we apply division lemma to 308 and 478, to get
478 = 308 x 1 + 170
Step 3: We consider the new divisor 308 and the new remainder 170, and apply the division lemma to get
308 = 170 x 1 + 138
We consider the new divisor 170 and the new remainder 138,and apply the division lemma to get
170 = 138 x 1 + 32
We consider the new divisor 138 and the new remainder 32,and apply the division lemma to get
138 = 32 x 4 + 10
We consider the new divisor 32 and the new remainder 10,and apply the division lemma to get
32 = 10 x 3 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 786 and 478 is 2
Notice that 2 = HCF(10,2) = HCF(32,10) = HCF(138,32) = HCF(170,138) = HCF(308,170) = HCF(478,308) = HCF(786,478) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 375 > 2, we apply the division lemma to 375 and 2, to get
375 = 2 x 187 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 375 is 1
Notice that 1 = HCF(2,1) = HCF(375,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 786, 478, 375?
Answer: HCF of 786, 478, 375 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 786, 478, 375 using Euclid's Algorithm?
Answer: For arbitrary numbers 786, 478, 375 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
