HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 376, 820, 782 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 376, 820, 782 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 376, 820, 782 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 376, 820, 782 is 2.
HCF(376, 820, 782) = 2
HCF of 376, 820, 782 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 376, 820, 782 is 2.
Highest Common Factor of 376,820,782 is 2
Step 1: Since 820 > 376, we apply the division lemma to 820 and 376, to get
820 = 376 x 2 + 68
Step 2: Since the reminder 376 ≠ 0, we apply division lemma to 68 and 376, to get
376 = 68 x 5 + 36
Step 3: 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 376 and 820 is 4
Notice that 4 = HCF(32,4) = HCF(36,32) = HCF(68,36) = HCF(376,68) = HCF(820,376) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 782 > 4, we apply the division lemma to 782 and 4, to get
782 = 4 x 195 + 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 782 is 2
Notice that 2 = HCF(4,2) = HCF(782,4) .
