HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 820, 167, 279 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 820, 167, 279 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 820, 167, 279 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 820, 167, 279 is 1.
HCF(820, 167, 279) = 1
HCF of 820, 167, 279 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 820, 167, 279 is 1.
Highest Common Factor of 820,167,279 is 1
Step 1: Since 820 > 167, we apply the division lemma to 820 and 167, to get
820 = 167 x 4 + 152
Step 2: Since the reminder 167 ≠ 0, we apply division lemma to 152 and 167, to get
167 = 152 x 1 + 15
Step 3: We consider the new divisor 152 and the new remainder 15, and apply the division lemma to get
152 = 15 x 10 + 2
We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get
15 = 2 x 7 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 820 and 167 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(152,15) = HCF(167,152) = HCF(820,167) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 279 > 1, we apply the division lemma to 279 and 1, to get
279 = 1 x 279 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 279 is 1
Notice that 1 = HCF(279,1) .
