HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 105, 630, 770 i.e. 35 the largest integer that leaves a remainder zero for all numbers.
HCF of 105, 630, 770 is 35 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 105, 630, 770 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 105, 630, 770 is 35.
HCF(105, 630, 770) = 35
HCF of 105, 630, 770 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 105, 630, 770 is 35.
Highest Common Factor of 105,630,770 is 35
Step 1: Since 630 > 105, we apply the division lemma to 630 and 105, to get
630 = 105 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 105, the HCF of 105 and 630 is 105
Notice that 105 = HCF(630,105) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 770 > 105, we apply the division lemma to 770 and 105, to get
770 = 105 x 7 + 35
Step 2: Since the reminder 105 ≠ 0, we apply division lemma to 35 and 105, to get
105 = 35 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 35, the HCF of 105 and 770 is 35
Notice that 35 = HCF(105,35) = HCF(770,105) .
