HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 256, 478, 657, 39 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 256, 478, 657, 39 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 256, 478, 657, 39 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 256, 478, 657, 39 is 1.
HCF(256, 478, 657, 39) = 1
HCF of 256, 478, 657, 39 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 256, 478, 657, 39 is 1.
Highest Common Factor of 256,478,657,39 is 1
Step 1: Since 478 > 256, we apply the division lemma to 478 and 256, to get
478 = 256 x 1 + 222
Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 222 and 256, to get
256 = 222 x 1 + 34
Step 3: We consider the new divisor 222 and the new remainder 34, and apply the division lemma to get
222 = 34 x 6 + 18
We consider the new divisor 34 and the new remainder 18,and apply the division lemma to get
34 = 18 x 1 + 16
We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get
18 = 16 x 1 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 256 and 478 is 2
Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(34,18) = HCF(222,34) = HCF(256,222) = HCF(478,256) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 657 > 2, we apply the division lemma to 657 and 2, to get
657 = 2 x 328 + 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 657 is 1
Notice that 1 = HCF(2,1) = HCF(657,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 39 > 1, we apply the division lemma to 39 and 1, 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 1 and 39 is 1
Notice that 1 = HCF(39,1) .
