HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 856, 2876, 7970 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 856, 2876, 7970 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 856, 2876, 7970 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 856, 2876, 7970 is 2.
HCF(856, 2876, 7970) = 2
HCF of 856, 2876, 7970 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 856, 2876, 7970 is 2.
Highest Common Factor of 856,2876,7970 is 2
Step 1: Since 2876 > 856, we apply the division lemma to 2876 and 856, to get
2876 = 856 x 3 + 308
Step 2: Since the reminder 856 ≠ 0, we apply division lemma to 308 and 856, to get
856 = 308 x 2 + 240
Step 3: We consider the new divisor 308 and the new remainder 240, and apply the division lemma to get
308 = 240 x 1 + 68
We consider the new divisor 240 and the new remainder 68,and apply the division lemma to get
240 = 68 x 3 + 36
We consider the new divisor 68 and the new remainder 36,and apply the division lemma to get
68 = 36 x 1 + 32
We consider the new divisor 36 and the new remainder 32,and apply the division lemma to get
36 = 32 x 1 + 4
We consider the new divisor 32 and the new remainder 4,and apply the division lemma to get
32 = 4 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 856 and 2876 is 4
Notice that 4 = HCF(32,4) = HCF(36,32) = HCF(68,36) = HCF(240,68) = HCF(308,240) = HCF(856,308) = HCF(2876,856) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7970 > 4, we apply the division lemma to 7970 and 4, to get
7970 = 4 x 1992 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 7970 is 2
Notice that 2 = HCF(4,2) = HCF(7970,4) .
