HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 608, 941, 649 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 608, 941, 649 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 608, 941, 649 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 608, 941, 649 is 1.
HCF(608, 941, 649) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 608, 941, 649 is 1.
Step 1: Since 941 > 608, we apply the division lemma to 941 and 608, to get
941 = 608 x 1 + 333
Step 2: Since the reminder 608 ≠ 0, we apply division lemma to 333 and 608, to get
608 = 333 x 1 + 275
Step 3: We consider the new divisor 333 and the new remainder 275, and apply the division lemma to get
333 = 275 x 1 + 58
We consider the new divisor 275 and the new remainder 58,and apply the division lemma to get
275 = 58 x 4 + 43
We consider the new divisor 58 and the new remainder 43,and apply the division lemma to get
58 = 43 x 1 + 15
We consider the new divisor 43 and the new remainder 15,and apply the division lemma to get
43 = 15 x 2 + 13
We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get
15 = 13 x 1 + 2
We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get
13 = 2 x 6 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 608 and 941 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(43,15) = HCF(58,43) = HCF(275,58) = HCF(333,275) = HCF(608,333) = HCF(941,608) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 649 > 1, we apply the division lemma to 649 and 1, to get
649 = 1 x 649 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 649 is 1
Notice that 1 = HCF(649,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
