HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 167, 420, 675 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 167, 420, 675 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 167, 420, 675 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 167, 420, 675 is 1.
HCF(167, 420, 675) = 1
HCF of 167, 420, 675 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 167, 420, 675 is 1.
Highest Common Factor of 167,420,675 is 1
Step 1: Since 420 > 167, we apply the division lemma to 420 and 167, to get
420 = 167 x 2 + 86
Step 2: Since the reminder 167 ≠ 0, we apply division lemma to 86 and 167, to get
167 = 86 x 1 + 81
Step 3: We consider the new divisor 86 and the new remainder 81, and apply the division lemma to get
86 = 81 x 1 + 5
We consider the new divisor 81 and the new remainder 5,and apply the division lemma to get
81 = 5 x 16 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 167 and 420 is 1
Notice that 1 = HCF(5,1) = HCF(81,5) = HCF(86,81) = HCF(167,86) = HCF(420,167) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 675 > 1, we apply the division lemma to 675 and 1, to get
675 = 1 x 675 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 675 is 1
Notice that 1 = HCF(675,1) .
