HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 670, 188, 100 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 670, 188, 100 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 670, 188, 100 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 670, 188, 100 is 2.
HCF(670, 188, 100) = 2
HCF of 670, 188, 100 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 670, 188, 100 is 2.
Highest Common Factor of 670,188,100 is 2
Step 1: Since 670 > 188, we apply the division lemma to 670 and 188, to get
670 = 188 x 3 + 106
Step 2: Since the reminder 188 ≠ 0, we apply division lemma to 106 and 188, to get
188 = 106 x 1 + 82
Step 3: We consider the new divisor 106 and the new remainder 82, and apply the division lemma to get
106 = 82 x 1 + 24
We consider the new divisor 82 and the new remainder 24,and apply the division lemma to get
82 = 24 x 3 + 10
We consider the new divisor 24 and the new remainder 10,and apply the division lemma to get
24 = 10 x 2 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma 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 670 and 188 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(24,10) = HCF(82,24) = HCF(106,82) = HCF(188,106) = HCF(670,188) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 100 > 2, we apply the division lemma to 100 and 2, to get
100 = 2 x 50 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 100 is 2
Notice that 2 = HCF(100,2) .
