HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 290, 478, 133, 771 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 290, 478, 133, 771 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 290, 478, 133, 771 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 290, 478, 133, 771 is 1.
HCF(290, 478, 133, 771) = 1
HCF of 290, 478, 133, 771 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 290, 478, 133, 771 is 1.
Highest Common Factor of 290,478,133,771 is 1
Step 1: Since 478 > 290, we apply the division lemma to 478 and 290, to get
478 = 290 x 1 + 188
Step 2: Since the reminder 290 ≠ 0, we apply division lemma to 188 and 290, to get
290 = 188 x 1 + 102
Step 3: We consider the new divisor 188 and the new remainder 102, and apply the division lemma to get
188 = 102 x 1 + 86
We consider the new divisor 102 and the new remainder 86,and apply the division lemma to get
102 = 86 x 1 + 16
We consider the new divisor 86 and the new remainder 16,and apply the division lemma to get
86 = 16 x 5 + 6
We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get
16 = 6 x 2 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 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 290 and 478 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(86,16) = HCF(102,86) = HCF(188,102) = HCF(290,188) = HCF(478,290) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 133 > 2, we apply the division lemma to 133 and 2, to get
133 = 2 x 66 + 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 133 is 1
Notice that 1 = HCF(2,1) = HCF(133,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 771 > 1, we apply the division lemma to 771 and 1, to get
771 = 1 x 771 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 771 is 1
Notice that 1 = HCF(771,1) .
