HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 181, 822, 373, 982 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 181, 822, 373, 982 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 181, 822, 373, 982 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 181, 822, 373, 982 is 1.
HCF(181, 822, 373, 982) = 1
HCF of 181, 822, 373, 982 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 181, 822, 373, 982 is 1.
Highest Common Factor of 181,822,373,982 is 1
Step 1: Since 822 > 181, we apply the division lemma to 822 and 181, to get
822 = 181 x 4 + 98
Step 2: Since the reminder 181 ≠ 0, we apply division lemma to 98 and 181, to get
181 = 98 x 1 + 83
Step 3: We consider the new divisor 98 and the new remainder 83, and apply the division lemma to get
98 = 83 x 1 + 15
We consider the new divisor 83 and the new remainder 15,and apply the division lemma to get
83 = 15 x 5 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 181 and 822 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(83,15) = HCF(98,83) = HCF(181,98) = HCF(822,181) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 373 > 1, we apply the division lemma to 373 and 1, to get
373 = 1 x 373 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 373 is 1
Notice that 1 = HCF(373,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 982 > 1, we apply the division lemma to 982 and 1, to get
982 = 1 x 982 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 982 is 1
Notice that 1 = HCF(982,1) .
