HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 673, 938, 440 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 673, 938, 440 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 673, 938, 440 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 673, 938, 440 is 1.
HCF(673, 938, 440) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 673, 938, 440 is 1.
Step 1: Since 938 > 673, we apply the division lemma to 938 and 673, to get
938 = 673 x 1 + 265
Step 2: Since the reminder 673 ≠ 0, we apply division lemma to 265 and 673, to get
673 = 265 x 2 + 143
Step 3: We consider the new divisor 265 and the new remainder 143, and apply the division lemma to get
265 = 143 x 1 + 122
We consider the new divisor 143 and the new remainder 122,and apply the division lemma to get
143 = 122 x 1 + 21
We consider the new divisor 122 and the new remainder 21,and apply the division lemma to get
122 = 21 x 5 + 17
We consider the new divisor 21 and the new remainder 17,and apply the division lemma to get
21 = 17 x 1 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 673 and 938 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(21,17) = HCF(122,21) = HCF(143,122) = HCF(265,143) = HCF(673,265) = HCF(938,673) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 440 > 1, we apply the division lemma to 440 and 1, to get
440 = 1 x 440 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 440 is 1
Notice that 1 = HCF(440,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
