HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 180, 872, 662 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 180, 872, 662 is 2 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 180, 872, 662 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 180, 872, 662 is 2.
HCF(180, 872, 662) = 2
HCF of 180, 872, 662 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 180, 872, 662 is 2.
Highest Common Factor of 180,872,662 is 2
Step 1: Since 872 > 180, we apply the division lemma to 872 and 180, to get
872 = 180 x 4 + 152
Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 152 and 180, to get
180 = 152 x 1 + 28
Step 3: We consider the new divisor 152 and the new remainder 28, and apply the division lemma to get
152 = 28 x 5 + 12
We consider the new divisor 28 and the new remainder 12,and apply the division lemma to get
28 = 12 x 2 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 180 and 872 is 4
Notice that 4 = HCF(12,4) = HCF(28,12) = HCF(152,28) = HCF(180,152) = HCF(872,180) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 662 > 4, we apply the division lemma to 662 and 4, to get
662 = 4 x 165 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 662 is 2
Notice that 2 = HCF(4,2) = HCF(662,4) .
