HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 338, 622, 930 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 338, 622, 930 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 338, 622, 930 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 338, 622, 930 is 2.
HCF(338, 622, 930) = 2
HCF of 338, 622, 930 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 338, 622, 930 is 2.
Highest Common Factor of 338,622,930 is 2
Step 1: Since 622 > 338, we apply the division lemma to 622 and 338, to get
622 = 338 x 1 + 284
Step 2: Since the reminder 338 ≠ 0, we apply division lemma to 284 and 338, to get
338 = 284 x 1 + 54
Step 3: We consider the new divisor 284 and the new remainder 54, and apply the division lemma to get
284 = 54 x 5 + 14
We consider the new divisor 54 and the new remainder 14,and apply the division lemma to get
54 = 14 x 3 + 12
We consider the new divisor 14 and the new remainder 12,and apply the division lemma to get
14 = 12 x 1 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 338 and 622 is 2
Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(54,14) = HCF(284,54) = HCF(338,284) = HCF(622,338) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 930 > 2, we apply the division lemma to 930 and 2, to get
930 = 2 x 465 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 930 is 2
Notice that 2 = HCF(930,2) .
