HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 602, 378, 398 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 602, 378, 398 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 602, 378, 398 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 602, 378, 398 is 2.
HCF(602, 378, 398) = 2
HCF of 602, 378, 398 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 602, 378, 398 is 2.
Highest Common Factor of 602,378,398 is 2
Step 1: Since 602 > 378, we apply the division lemma to 602 and 378, to get
602 = 378 x 1 + 224
Step 2: Since the reminder 378 ≠ 0, we apply division lemma to 224 and 378, to get
378 = 224 x 1 + 154
Step 3: We consider the new divisor 224 and the new remainder 154, and apply the division lemma to get
224 = 154 x 1 + 70
We consider the new divisor 154 and the new remainder 70,and apply the division lemma to get
154 = 70 x 2 + 14
We consider the new divisor 70 and the new remainder 14,and apply the division lemma to get
70 = 14 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 602 and 378 is 14
Notice that 14 = HCF(70,14) = HCF(154,70) = HCF(224,154) = HCF(378,224) = HCF(602,378) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 398 > 14, we apply the division lemma to 398 and 14, to get
398 = 14 x 28 + 6
Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 6 and 14, to get
14 = 6 x 2 + 2
Step 3: We consider the new divisor 6 and the new remainder 2, and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 14 and 398 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(398,14) .
