HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 641, 908, 305 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 641, 908, 305 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 641, 908, 305 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 641, 908, 305 is 1.
HCF(641, 908, 305) = 1
HCF of 641, 908, 305 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 641, 908, 305 is 1.
Highest Common Factor of 641,908,305 is 1
Step 1: Since 908 > 641, we apply the division lemma to 908 and 641, to get
908 = 641 x 1 + 267
Step 2: Since the reminder 641 ≠ 0, we apply division lemma to 267 and 641, to get
641 = 267 x 2 + 107
Step 3: We consider the new divisor 267 and the new remainder 107, and apply the division lemma to get
267 = 107 x 2 + 53
We consider the new divisor 107 and the new remainder 53,and apply the division lemma to get
107 = 53 x 2 + 1
We consider the new divisor 53 and the new remainder 1,and apply the division lemma to get
53 = 1 x 53 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 641 and 908 is 1
Notice that 1 = HCF(53,1) = HCF(107,53) = HCF(267,107) = HCF(641,267) = HCF(908,641) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 305 > 1, we apply the division lemma to 305 and 1, to get
305 = 1 x 305 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 305 is 1
Notice that 1 = HCF(305,1) .
