HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 307, 421, 722, 230 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 307, 421, 722, 230 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 307, 421, 722, 230 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 307, 421, 722, 230 is 1.
HCF(307, 421, 722, 230) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 307, 421, 722, 230 is 1.
Step 1: Since 421 > 307, we apply the division lemma to 421 and 307, to get
421 = 307 x 1 + 114
Step 2: Since the reminder 307 ≠ 0, we apply division lemma to 114 and 307, to get
307 = 114 x 2 + 79
Step 3: We consider the new divisor 114 and the new remainder 79, and apply the division lemma to get
114 = 79 x 1 + 35
We consider the new divisor 79 and the new remainder 35,and apply the division lemma to get
79 = 35 x 2 + 9
We consider the new divisor 35 and the new remainder 9,and apply the division lemma to get
35 = 9 x 3 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 307 and 421 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(35,9) = HCF(79,35) = HCF(114,79) = HCF(307,114) = HCF(421,307) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 722 > 1, we apply the division lemma to 722 and 1, to get
722 = 1 x 722 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 722 is 1
Notice that 1 = HCF(722,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 230 > 1, we apply the division lemma to 230 and 1, to get
230 = 1 x 230 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 230 is 1
Notice that 1 = HCF(230,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
