HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 807, 690, 25, 475 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 807, 690, 25, 475 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, 690, 25, 475 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, 690, 25, 475 is 1.
HCF(807, 690, 25, 475) = 1
HCF of 807, 690, 25, 475 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, 690, 25, 475 is 1.
Highest Common Factor of 807,690,25,475 is 1
Step 1: Since 807 > 690, we apply the division lemma to 807 and 690, to get
807 = 690 x 1 + 117
Step 2: Since the reminder 690 ≠ 0, we apply division lemma to 117 and 690, to get
690 = 117 x 5 + 105
Step 3: We consider the new divisor 117 and the new remainder 105, and apply the division lemma to get
117 = 105 x 1 + 12
We consider the new divisor 105 and the new remainder 12,and apply the division lemma to get
105 = 12 x 8 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 807 and 690 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(105,12) = HCF(117,105) = HCF(690,117) = HCF(807,690) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 25 > 3, we apply the division lemma to 25 and 3, to get
25 = 3 x 8 + 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 25 is 1
Notice that 1 = HCF(3,1) = HCF(25,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 475 > 1, we apply the division lemma to 475 and 1, to get
475 = 1 x 475 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 475 is 1
Notice that 1 = HCF(475,1) .
