HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 398, 482, 983, 788 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 398, 482, 983, 788 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 398, 482, 983, 788 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 398, 482, 983, 788 is 1.
HCF(398, 482, 983, 788) = 1
HCF of 398, 482, 983, 788 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 398, 482, 983, 788 is 1.
Highest Common Factor of 398,482,983,788 is 1
Step 1: Since 482 > 398, we apply the division lemma to 482 and 398, to get
482 = 398 x 1 + 84
Step 2: Since the reminder 398 ≠ 0, we apply division lemma to 84 and 398, to get
398 = 84 x 4 + 62
Step 3: We consider the new divisor 84 and the new remainder 62, and apply the division lemma to get
84 = 62 x 1 + 22
We consider the new divisor 62 and the new remainder 22,and apply the division lemma to get
62 = 22 x 2 + 18
We consider the new divisor 22 and the new remainder 18,and apply the division lemma to get
22 = 18 x 1 + 4
We consider the new divisor 18 and the new remainder 4,and apply the division lemma to get
18 = 4 x 4 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 398 and 482 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(22,18) = HCF(62,22) = HCF(84,62) = HCF(398,84) = HCF(482,398) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 983 > 2, we apply the division lemma to 983 and 2, to get
983 = 2 x 491 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 983 is 1
Notice that 1 = HCF(2,1) = HCF(983,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 788 > 1, we apply the division lemma to 788 and 1, to get
788 = 1 x 788 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 788 is 1
Notice that 1 = HCF(788,1) .
