HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 275, 982, 71, 149 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 275, 982, 71, 149 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 275, 982, 71, 149 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 275, 982, 71, 149 is 1.
HCF(275, 982, 71, 149) = 1
HCF of 275, 982, 71, 149 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 275, 982, 71, 149 is 1.
Highest Common Factor of 275,982,71,149 is 1
Step 1: Since 982 > 275, we apply the division lemma to 982 and 275, to get
982 = 275 x 3 + 157
Step 2: Since the reminder 275 ≠ 0, we apply division lemma to 157 and 275, to get
275 = 157 x 1 + 118
Step 3: We consider the new divisor 157 and the new remainder 118, and apply the division lemma to get
157 = 118 x 1 + 39
We consider the new divisor 118 and the new remainder 39,and apply the division lemma to get
118 = 39 x 3 + 1
We consider the new divisor 39 and the new remainder 1,and apply the division lemma to get
39 = 1 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 275 and 982 is 1
Notice that 1 = HCF(39,1) = HCF(118,39) = HCF(157,118) = HCF(275,157) = HCF(982,275) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 71 > 1, we apply the division lemma to 71 and 1, to get
71 = 1 x 71 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 71 is 1
Notice that 1 = HCF(71,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 149 > 1, we apply the division lemma to 149 and 1, to get
149 = 1 x 149 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 149 is 1
Notice that 1 = HCF(149,1) .
