HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 863, 752, 421, 670 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 863, 752, 421, 670 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, 752, 421, 670 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, 752, 421, 670 is 1.
HCF(863, 752, 421, 670) = 1
HCF of 863, 752, 421, 670 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 863, 752, 421, 670 is 1.
Highest Common Factor of 863,752,421,670 is 1
Step 1: Since 863 > 752, we apply the division lemma to 863 and 752, to get
863 = 752 x 1 + 111
Step 2: Since the reminder 752 ≠ 0, we apply division lemma to 111 and 752, to get
752 = 111 x 6 + 86
Step 3: We consider the new divisor 111 and the new remainder 86, and apply the division lemma to get
111 = 86 x 1 + 25
We consider the new divisor 86 and the new remainder 25,and apply the division lemma to get
86 = 25 x 3 + 11
We consider the new divisor 25 and the new remainder 11,and apply the division lemma to get
25 = 11 x 2 + 3
We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get
11 = 3 x 3 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 863 and 752 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(25,11) = HCF(86,25) = HCF(111,86) = HCF(752,111) = HCF(863,752) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 421 > 1, we apply the division lemma to 421 and 1, to get
421 = 1 x 421 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 421 is 1
Notice that 1 = HCF(421,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 670 > 1, we apply the division lemma to 670 and 1, to get
670 = 1 x 670 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 670 is 1
Notice that 1 = HCF(670,1) .
