HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 653, 521, 636, 800 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 653, 521, 636, 800 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, 521, 636, 800 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, 521, 636, 800 is 1.
HCF(653, 521, 636, 800) = 1
HCF of 653, 521, 636, 800 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, 521, 636, 800 is 1.
Highest Common Factor of 653,521,636,800 is 1
Step 1: Since 653 > 521, we apply the division lemma to 653 and 521, to get
653 = 521 x 1 + 132
Step 2: Since the reminder 521 ≠ 0, we apply division lemma to 132 and 521, to get
521 = 132 x 3 + 125
Step 3: We consider the new divisor 132 and the new remainder 125, and apply the division lemma to get
132 = 125 x 1 + 7
We consider the new divisor 125 and the new remainder 7,and apply the division lemma to get
125 = 7 x 17 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 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 653 and 521 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(125,7) = HCF(132,125) = HCF(521,132) = HCF(653,521) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 636 > 1, we apply the division lemma to 636 and 1, to get
636 = 1 x 636 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 636 is 1
Notice that 1 = HCF(636,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 800 > 1, we apply the division lemma to 800 and 1, to get
800 = 1 x 800 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 800 is 1
Notice that 1 = HCF(800,1) .
