HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 807, 585, 465, 253 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 807, 585, 465, 253 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 807, 585, 465, 253 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 807, 585, 465, 253 is 1.
HCF(807, 585, 465, 253) = 1
HCF of 807, 585, 465, 253 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 807, 585, 465, 253 is 1.
Highest Common Factor of 807,585,465,253 is 1
Step 1: Since 807 > 585, we apply the division lemma to 807 and 585, to get
807 = 585 x 1 + 222
Step 2: Since the reminder 585 ≠ 0, we apply division lemma to 222 and 585, to get
585 = 222 x 2 + 141
Step 3: We consider the new divisor 222 and the new remainder 141, and apply the division lemma to get
222 = 141 x 1 + 81
We consider the new divisor 141 and the new remainder 81,and apply the division lemma to get
141 = 81 x 1 + 60
We consider the new divisor 81 and the new remainder 60,and apply the division lemma to get
81 = 60 x 1 + 21
We consider the new divisor 60 and the new remainder 21,and apply the division lemma to get
60 = 21 x 2 + 18
We consider the new divisor 21 and the new remainder 18,and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 807 and 585 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(60,21) = HCF(81,60) = HCF(141,81) = HCF(222,141) = HCF(585,222) = HCF(807,585) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 465 > 3, we apply the division lemma to 465 and 3, to get
465 = 3 x 155 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 465 is 3
Notice that 3 = HCF(465,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 253 > 3, we apply the division lemma to 253 and 3, to get
253 = 3 x 84 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 253 is 1
Notice that 1 = HCF(3,1) = HCF(253,3) .
