HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 975, 858, 389 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 975, 858, 389 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 975, 858, 389 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 975, 858, 389 is 1.
HCF(975, 858, 389) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 975, 858, 389 is 1.
Step 1: Since 975 > 858, we apply the division lemma to 975 and 858, to get
975 = 858 x 1 + 117
Step 2: Since the reminder 858 ≠ 0, we apply division lemma to 117 and 858, to get
858 = 117 x 7 + 39
Step 3: We consider the new divisor 117 and the new remainder 39, and apply the division lemma to get
117 = 39 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 39, the HCF of 975 and 858 is 39
Notice that 39 = HCF(117,39) = HCF(858,117) = HCF(975,858) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 389 > 39, we apply the division lemma to 389 and 39, to get
389 = 39 x 9 + 38
Step 2: Since the reminder 39 ≠ 0, we apply division lemma to 38 and 39, to get
39 = 38 x 1 + 1
Step 3: We consider the new divisor 38 and the new remainder 1, and apply the division lemma to get
38 = 1 x 38 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 39 and 389 is 1
Notice that 1 = HCF(38,1) = HCF(39,38) = HCF(389,39) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 975, 858, 389?
Answer: HCF of 975, 858, 389 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 975, 858, 389 using Euclid's Algorithm?
Answer: For arbitrary numbers 975, 858, 389 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
