HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 863, 158, 771, 386 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 863, 158, 771, 386 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 863, 158, 771, 386 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 863, 158, 771, 386 is 1.
HCF(863, 158, 771, 386) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 863, 158, 771, 386 is 1.
Step 1: Since 863 > 158, we apply the division lemma to 863 and 158, to get
863 = 158 x 5 + 73
Step 2: Since the reminder 158 ≠ 0, we apply division lemma to 73 and 158, to get
158 = 73 x 2 + 12
Step 3: We consider the new divisor 73 and the new remainder 12, and apply the division lemma to get
73 = 12 x 6 + 1
We consider the new divisor 12 and the new remainder 1, and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 863 and 158 is 1
Notice that 1 = HCF(12,1) = HCF(73,12) = HCF(158,73) = HCF(863,158) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 771 > 1, we apply the division lemma to 771 and 1, to get
771 = 1 x 771 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 771 is 1
Notice that 1 = HCF(771,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 386 > 1, we apply the division lemma to 386 and 1, to get
386 = 1 x 386 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 386 is 1
Notice that 1 = HCF(386,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
