HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 640, 394, 976 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 640, 394, 976 is 2 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 640, 394, 976 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 640, 394, 976 is 2.
HCF(640, 394, 976) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 640, 394, 976 is 2.
Step 1: Since 640 > 394, we apply the division lemma to 640 and 394, to get
640 = 394 x 1 + 246
Step 2: Since the reminder 394 ≠ 0, we apply division lemma to 246 and 394, to get
394 = 246 x 1 + 148
Step 3: We consider the new divisor 246 and the new remainder 148, and apply the division lemma to get
246 = 148 x 1 + 98
We consider the new divisor 148 and the new remainder 98,and apply the division lemma to get
148 = 98 x 1 + 50
We consider the new divisor 98 and the new remainder 50,and apply the division lemma to get
98 = 50 x 1 + 48
We consider the new divisor 50 and the new remainder 48,and apply the division lemma to get
50 = 48 x 1 + 2
We consider the new divisor 48 and the new remainder 2,and apply the division lemma to get
48 = 2 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 640 and 394 is 2
Notice that 2 = HCF(48,2) = HCF(50,48) = HCF(98,50) = HCF(148,98) = HCF(246,148) = HCF(394,246) = HCF(640,394) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 976 > 2, we apply the division lemma to 976 and 2, to get
976 = 2 x 488 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 976 is 2
Notice that 2 = HCF(976,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 640, 394, 976?
Answer: HCF of 640, 394, 976 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 640, 394, 976 using Euclid's Algorithm?
Answer: For arbitrary numbers 640, 394, 976 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
