HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 649, 290, 186 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 649, 290, 186 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 649, 290, 186 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 649, 290, 186 is 1.
HCF(649, 290, 186) = 1
HCF of 649, 290, 186 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 649, 290, 186 is 1.
Highest Common Factor of 649,290,186 is 1
Step 1: Since 649 > 290, we apply the division lemma to 649 and 290, to get
649 = 290 x 2 + 69
Step 2: Since the reminder 290 ≠ 0, we apply division lemma to 69 and 290, to get
290 = 69 x 4 + 14
Step 3: We consider the new divisor 69 and the new remainder 14, and apply the division lemma to get
69 = 14 x 4 + 13
We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get
14 = 13 x 1 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 649 and 290 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(69,14) = HCF(290,69) = HCF(649,290) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 186 > 1, we apply the division lemma to 186 and 1, to get
186 = 1 x 186 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 186 is 1
Notice that 1 = HCF(186,1) .
