HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 256, 635, 898, 723 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 256, 635, 898, 723 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 256, 635, 898, 723 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 256, 635, 898, 723 is 1.
HCF(256, 635, 898, 723) = 1
HCF of 256, 635, 898, 723 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 256, 635, 898, 723 is 1.
Highest Common Factor of 256,635,898,723 is 1
Step 1: Since 635 > 256, we apply the division lemma to 635 and 256, to get
635 = 256 x 2 + 123
Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 123 and 256, to get
256 = 123 x 2 + 10
Step 3: We consider the new divisor 123 and the new remainder 10, and apply the division lemma to get
123 = 10 x 12 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 256 and 635 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(123,10) = HCF(256,123) = HCF(635,256) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 898 > 1, we apply the division lemma to 898 and 1, to get
898 = 1 x 898 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 898 is 1
Notice that 1 = HCF(898,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 723 > 1, we apply the division lemma to 723 and 1, to get
723 = 1 x 723 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 723 is 1
Notice that 1 = HCF(723,1) .
