HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 896, 408, 649, 257 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 896, 408, 649, 257 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 896, 408, 649, 257 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 896, 408, 649, 257 is 1.
HCF(896, 408, 649, 257) = 1
HCF of 896, 408, 649, 257 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 896, 408, 649, 257 is 1.
Highest Common Factor of 896,408,649,257 is 1
Step 1: Since 896 > 408, we apply the division lemma to 896 and 408, to get
896 = 408 x 2 + 80
Step 2: Since the reminder 408 ≠ 0, we apply division lemma to 80 and 408, to get
408 = 80 x 5 + 8
Step 3: We consider the new divisor 80 and the new remainder 8, and apply the division lemma to get
80 = 8 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 896 and 408 is 8
Notice that 8 = HCF(80,8) = HCF(408,80) = HCF(896,408) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 649 > 8, we apply the division lemma to 649 and 8, to get
649 = 8 x 81 + 1
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 1 and 8, to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 8 and 649 is 1
Notice that 1 = HCF(8,1) = HCF(649,8) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 257 > 1, we apply the division lemma to 257 and 1, to get
257 = 1 x 257 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 257 is 1
Notice that 1 = HCF(257,1) .
