HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 842, 387, 862, 977 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 842, 387, 862, 977 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 842, 387, 862, 977 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 842, 387, 862, 977 is 1.
HCF(842, 387, 862, 977) = 1
HCF of 842, 387, 862, 977 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 842, 387, 862, 977 is 1.
Highest Common Factor of 842,387,862,977 is 1
Step 1: Since 842 > 387, we apply the division lemma to 842 and 387, to get
842 = 387 x 2 + 68
Step 2: Since the reminder 387 ≠ 0, we apply division lemma to 68 and 387, to get
387 = 68 x 5 + 47
Step 3: We consider the new divisor 68 and the new remainder 47, and apply the division lemma to get
68 = 47 x 1 + 21
We consider the new divisor 47 and the new remainder 21,and apply the division lemma to get
47 = 21 x 2 + 5
We consider the new divisor 21 and the new remainder 5,and apply the division lemma to get
21 = 5 x 4 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 842 and 387 is 1
Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(47,21) = HCF(68,47) = HCF(387,68) = HCF(842,387) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 862 > 1, we apply the division lemma to 862 and 1, to get
862 = 1 x 862 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 862 is 1
Notice that 1 = HCF(862,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 977 > 1, we apply the division lemma to 977 and 1, to get
977 = 1 x 977 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 977 is 1
Notice that 1 = HCF(977,1) .
