HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 557, 965, 128 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 557, 965, 128 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 557, 965, 128 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 557, 965, 128 is 1.
HCF(557, 965, 128) = 1
HCF of 557, 965, 128 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 557, 965, 128 is 1.
Highest Common Factor of 557,965,128 is 1
Step 1: Since 965 > 557, we apply the division lemma to 965 and 557, to get
965 = 557 x 1 + 408
Step 2: Since the reminder 557 ≠ 0, we apply division lemma to 408 and 557, to get
557 = 408 x 1 + 149
Step 3: We consider the new divisor 408 and the new remainder 149, and apply the division lemma to get
408 = 149 x 2 + 110
We consider the new divisor 149 and the new remainder 110,and apply the division lemma to get
149 = 110 x 1 + 39
We consider the new divisor 110 and the new remainder 39,and apply the division lemma to get
110 = 39 x 2 + 32
We consider the new divisor 39 and the new remainder 32,and apply the division lemma to get
39 = 32 x 1 + 7
We consider the new divisor 32 and the new remainder 7,and apply the division lemma to get
32 = 7 x 4 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 557 and 965 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(32,7) = HCF(39,32) = HCF(110,39) = HCF(149,110) = HCF(408,149) = HCF(557,408) = HCF(965,557) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 128 > 1, we apply the division lemma to 128 and 1, to get
128 = 1 x 128 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 128 is 1
Notice that 1 = HCF(128,1) .
