HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 377, 639, 207 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 377, 639, 207 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 377, 639, 207 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 377, 639, 207 is 1.
HCF(377, 639, 207) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 377, 639, 207 is 1.
Step 1: Since 639 > 377, we apply the division lemma to 639 and 377, to get
639 = 377 x 1 + 262
Step 2: Since the reminder 377 ≠ 0, we apply division lemma to 262 and 377, to get
377 = 262 x 1 + 115
Step 3: We consider the new divisor 262 and the new remainder 115, and apply the division lemma to get
262 = 115 x 2 + 32
We consider the new divisor 115 and the new remainder 32,and apply the division lemma to get
115 = 32 x 3 + 19
We consider the new divisor 32 and the new remainder 19,and apply the division lemma to get
32 = 19 x 1 + 13
We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get
19 = 13 x 1 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 377 and 639 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(32,19) = HCF(115,32) = HCF(262,115) = HCF(377,262) = HCF(639,377) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 207 > 1, we apply the division lemma to 207 and 1, to get
207 = 1 x 207 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 207 is 1
Notice that 1 = HCF(207,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
