HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 347, 231, 942 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 485, 347, 231, 942 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 485, 347, 231, 942 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 485, 347, 231, 942 is 1.
HCF(485, 347, 231, 942) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 485, 347, 231, 942 is 1.
Step 1: Since 485 > 347, we apply the division lemma to 485 and 347, to get
485 = 347 x 1 + 138
Step 2: Since the reminder 347 ≠ 0, we apply division lemma to 138 and 347, to get
347 = 138 x 2 + 71
Step 3: We consider the new divisor 138 and the new remainder 71, and apply the division lemma to get
138 = 71 x 1 + 67
We consider the new divisor 71 and the new remainder 67,and apply the division lemma to get
71 = 67 x 1 + 4
We consider the new divisor 67 and the new remainder 4,and apply the division lemma to get
67 = 4 x 16 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 485 and 347 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(67,4) = HCF(71,67) = HCF(138,71) = HCF(347,138) = HCF(485,347) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 231 > 1, we apply the division lemma to 231 and 1, to get
231 = 1 x 231 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 231 is 1
Notice that 1 = HCF(231,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 942 > 1, we apply the division lemma to 942 and 1, to get
942 = 1 x 942 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 942 is 1
Notice that 1 = HCF(942,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
