HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 490, 623, 167 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 490, 623, 167 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 490, 623, 167 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 490, 623, 167 is 1.
HCF(490, 623, 167) = 1
HCF of 490, 623, 167 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 490, 623, 167 is 1.
Highest Common Factor of 490,623,167 is 1
Step 1: Since 623 > 490, we apply the division lemma to 623 and 490, to get
623 = 490 x 1 + 133
Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 133 and 490, to get
490 = 133 x 3 + 91
Step 3: We consider the new divisor 133 and the new remainder 91, and apply the division lemma to get
133 = 91 x 1 + 42
We consider the new divisor 91 and the new remainder 42,and apply the division lemma to get
91 = 42 x 2 + 7
We consider the new divisor 42 and the new remainder 7,and apply the division lemma to get
42 = 7 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 490 and 623 is 7
Notice that 7 = HCF(42,7) = HCF(91,42) = HCF(133,91) = HCF(490,133) = HCF(623,490) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 167 > 7, we apply the division lemma to 167 and 7, to get
167 = 7 x 23 + 6
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 6 and 7, to get
7 = 6 x 1 + 1
Step 3: We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 167 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(167,7) .
