HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 268, 731, 647, 674 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 268, 731, 647, 674 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 268, 731, 647, 674 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 268, 731, 647, 674 is 1.
HCF(268, 731, 647, 674) = 1
HCF of 268, 731, 647, 674 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 268, 731, 647, 674 is 1.
Highest Common Factor of 268,731,647,674 is 1
Step 1: Since 731 > 268, we apply the division lemma to 731 and 268, to get
731 = 268 x 2 + 195
Step 2: Since the reminder 268 ≠ 0, we apply division lemma to 195 and 268, to get
268 = 195 x 1 + 73
Step 3: We consider the new divisor 195 and the new remainder 73, and apply the division lemma to get
195 = 73 x 2 + 49
We consider the new divisor 73 and the new remainder 49,and apply the division lemma to get
73 = 49 x 1 + 24
We consider the new divisor 49 and the new remainder 24,and apply the division lemma to get
49 = 24 x 2 + 1
We consider the new divisor 24 and the new remainder 1,and apply the division lemma to get
24 = 1 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 268 and 731 is 1
Notice that 1 = HCF(24,1) = HCF(49,24) = HCF(73,49) = HCF(195,73) = HCF(268,195) = HCF(731,268) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 647 > 1, we apply the division lemma to 647 and 1, to get
647 = 1 x 647 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 647 is 1
Notice that 1 = HCF(647,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 674 > 1, we apply the division lemma to 674 and 1, to get
674 = 1 x 674 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 674 is 1
Notice that 1 = HCF(674,1) .
