HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 664, 256 i.e. 8 the largest integer that leaves a remainder zero for all numbers.
HCF of 664, 256 is 8 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 664, 256 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 664, 256 is 8.
HCF(664, 256) = 8
HCF of 664, 256 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 664, 256 is 8.
Highest Common Factor of 664,256 is 8
Step 1: Since 664 > 256, we apply the division lemma to 664 and 256, to get
664 = 256 x 2 + 152
Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 152 and 256, to get
256 = 152 x 1 + 104
Step 3: We consider the new divisor 152 and the new remainder 104, and apply the division lemma to get
152 = 104 x 1 + 48
We consider the new divisor 104 and the new remainder 48,and apply the division lemma to get
104 = 48 x 2 + 8
We consider the new divisor 48 and the new remainder 8,and apply the division lemma to get
48 = 8 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 664 and 256 is 8
Notice that 8 = HCF(48,8) = HCF(104,48) = HCF(152,104) = HCF(256,152) = HCF(664,256) .
