HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 620, 794, 858 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 620, 794, 858 is 2 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 620, 794, 858 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 620, 794, 858 is 2.
HCF(620, 794, 858) = 2
HCF of 620, 794, 858 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 620, 794, 858 is 2.
Highest Common Factor of 620,794,858 is 2
Step 1: Since 794 > 620, we apply the division lemma to 794 and 620, to get
794 = 620 x 1 + 174
Step 2: Since the reminder 620 ≠ 0, we apply division lemma to 174 and 620, to get
620 = 174 x 3 + 98
Step 3: We consider the new divisor 174 and the new remainder 98, and apply the division lemma to get
174 = 98 x 1 + 76
We consider the new divisor 98 and the new remainder 76,and apply the division lemma to get
98 = 76 x 1 + 22
We consider the new divisor 76 and the new remainder 22,and apply the division lemma to get
76 = 22 x 3 + 10
We consider the new divisor 22 and the new remainder 10,and apply the division lemma to get
22 = 10 x 2 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 620 and 794 is 2
Notice that 2 = HCF(10,2) = HCF(22,10) = HCF(76,22) = HCF(98,76) = HCF(174,98) = HCF(620,174) = HCF(794,620) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 858 > 2, we apply the division lemma to 858 and 2, to get
858 = 2 x 429 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 858 is 2
Notice that 2 = HCF(858,2) .
