HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 119, 399, 210 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 119, 399, 210 is 7 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 119, 399, 210 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 119, 399, 210 is 7.
HCF(119, 399, 210) = 7
HCF of 119, 399, 210 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 119, 399, 210 is 7.
Highest Common Factor of 119,399,210 is 7
Step 1: Since 399 > 119, we apply the division lemma to 399 and 119, to get
399 = 119 x 3 + 42
Step 2: Since the reminder 119 ≠ 0, we apply division lemma to 42 and 119, to get
119 = 42 x 2 + 35
Step 3: We consider the new divisor 42 and the new remainder 35, and apply the division lemma to get
42 = 35 x 1 + 7
We consider the new divisor 35 and the new remainder 7, and apply the division lemma to get
35 = 7 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 119 and 399 is 7
Notice that 7 = HCF(35,7) = HCF(42,35) = HCF(119,42) = HCF(399,119) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 210 > 7, we apply the division lemma to 210 and 7, to get
210 = 7 x 30 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 7 and 210 is 7
Notice that 7 = HCF(210,7) .
