HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 842, 351, 431, 340 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 842, 351, 431, 340 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, 351, 431, 340 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, 351, 431, 340 is 1.
HCF(842, 351, 431, 340) = 1
HCF of 842, 351, 431, 340 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, 351, 431, 340 is 1.
Highest Common Factor of 842,351,431,340 is 1
Step 1: Since 842 > 351, we apply the division lemma to 842 and 351, to get
842 = 351 x 2 + 140
Step 2: Since the reminder 351 ≠ 0, we apply division lemma to 140 and 351, to get
351 = 140 x 2 + 71
Step 3: We consider the new divisor 140 and the new remainder 71, and apply the division lemma to get
140 = 71 x 1 + 69
We consider the new divisor 71 and the new remainder 69,and apply the division lemma to get
71 = 69 x 1 + 2
We consider the new divisor 69 and the new remainder 2,and apply the division lemma to get
69 = 2 x 34 + 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 842 and 351 is 1
Notice that 1 = HCF(2,1) = HCF(69,2) = HCF(71,69) = HCF(140,71) = HCF(351,140) = HCF(842,351) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 431 > 1, we apply the division lemma to 431 and 1, to get
431 = 1 x 431 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 431 is 1
Notice that 1 = HCF(431,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 340 > 1, we apply the division lemma to 340 and 1, to get
340 = 1 x 340 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 340 is 1
Notice that 1 = HCF(340,1) .
