HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 664, 908 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 664, 908 is 4 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, 908 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, 908 is 4.
HCF(664, 908) = 4
HCF of 664, 908 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, 908 is 4.
Highest Common Factor of 664,908 is 4
Step 1: Since 908 > 664, we apply the division lemma to 908 and 664, to get
908 = 664 x 1 + 244
Step 2: Since the reminder 664 ≠ 0, we apply division lemma to 244 and 664, to get
664 = 244 x 2 + 176
Step 3: We consider the new divisor 244 and the new remainder 176, and apply the division lemma to get
244 = 176 x 1 + 68
We consider the new divisor 176 and the new remainder 68,and apply the division lemma to get
176 = 68 x 2 + 40
We consider the new divisor 68 and the new remainder 40,and apply the division lemma to get
68 = 40 x 1 + 28
We consider the new divisor 40 and the new remainder 28,and apply the division lemma to get
40 = 28 x 1 + 12
We consider the new divisor 28 and the new remainder 12,and apply the division lemma to get
28 = 12 x 2 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 664 and 908 is 4
Notice that 4 = HCF(12,4) = HCF(28,12) = HCF(40,28) = HCF(68,40) = HCF(176,68) = HCF(244,176) = HCF(664,244) = HCF(908,664) .
