HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 175, 245, 666 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 175, 245, 666 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 175, 245, 666 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 175, 245, 666 is 1.
HCF(175, 245, 666) = 1
HCF of 175, 245, 666 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 175, 245, 666 is 1.
Highest Common Factor of 175,245,666 is 1
Step 1: Since 245 > 175, we apply the division lemma to 245 and 175, to get
245 = 175 x 1 + 70
Step 2: Since the reminder 175 ≠ 0, we apply division lemma to 70 and 175, to get
175 = 70 x 2 + 35
Step 3: We consider the new divisor 70 and the new remainder 35, and apply the division lemma to get
70 = 35 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 35, the HCF of 175 and 245 is 35
Notice that 35 = HCF(70,35) = HCF(175,70) = HCF(245,175) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 666 > 35, we apply the division lemma to 666 and 35, to get
666 = 35 x 19 + 1
Step 2: Since the reminder 35 ≠ 0, we apply division lemma to 1 and 35, to get
35 = 1 x 35 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 35 and 666 is 1
Notice that 1 = HCF(35,1) = HCF(666,35) .
