HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 693, 858, 478 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 693, 858, 478 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 693, 858, 478 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 693, 858, 478 is 1.
HCF(693, 858, 478) = 1
HCF of 693, 858, 478 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 693, 858, 478 is 1.
Highest Common Factor of 693,858,478 is 1
Step 1: Since 858 > 693, we apply the division lemma to 858 and 693, to get
858 = 693 x 1 + 165
Step 2: Since the reminder 693 ≠ 0, we apply division lemma to 165 and 693, to get
693 = 165 x 4 + 33
Step 3: We consider the new divisor 165 and the new remainder 33, and apply the division lemma to get
165 = 33 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 33, the HCF of 693 and 858 is 33
Notice that 33 = HCF(165,33) = HCF(693,165) = HCF(858,693) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 478 > 33, we apply the division lemma to 478 and 33, to get
478 = 33 x 14 + 16
Step 2: Since the reminder 33 ≠ 0, we apply division lemma to 16 and 33, to get
33 = 16 x 2 + 1
Step 3: We consider the new divisor 16 and the new remainder 1, and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 33 and 478 is 1
Notice that 1 = HCF(16,1) = HCF(33,16) = HCF(478,33) .
