HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 653, 153, 864 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 653, 153, 864 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 653, 153, 864 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 653, 153, 864 is 1.
HCF(653, 153, 864) = 1
HCF of 653, 153, 864 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 653, 153, 864 is 1.
Highest Common Factor of 653,153,864 is 1
Step 1: Since 653 > 153, we apply the division lemma to 653 and 153, to get
653 = 153 x 4 + 41
Step 2: Since the reminder 153 ≠ 0, we apply division lemma to 41 and 153, to get
153 = 41 x 3 + 30
Step 3: We consider the new divisor 41 and the new remainder 30, and apply the division lemma to get
41 = 30 x 1 + 11
We consider the new divisor 30 and the new remainder 11,and apply the division lemma to get
30 = 11 x 2 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 653 and 153 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(30,11) = HCF(41,30) = HCF(153,41) = HCF(653,153) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 864 > 1, we apply the division lemma to 864 and 1, to get
864 = 1 x 864 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 864 is 1
Notice that 1 = HCF(864,1) .
