HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 642, 702, 614 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 642, 702, 614 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 642, 702, 614 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 642, 702, 614 is 2.
HCF(642, 702, 614) = 2
HCF of 642, 702, 614 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 642, 702, 614 is 2.
Highest Common Factor of 642,702,614 is 2
Step 1: Since 702 > 642, we apply the division lemma to 702 and 642, to get
702 = 642 x 1 + 60
Step 2: Since the reminder 642 ≠ 0, we apply division lemma to 60 and 642, to get
642 = 60 x 10 + 42
Step 3: We consider the new divisor 60 and the new remainder 42, and apply the division lemma to get
60 = 42 x 1 + 18
We consider the new divisor 42 and the new remainder 18,and apply the division lemma to get
42 = 18 x 2 + 6
We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get
18 = 6 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 642 and 702 is 6
Notice that 6 = HCF(18,6) = HCF(42,18) = HCF(60,42) = HCF(642,60) = HCF(702,642) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 614 > 6, we apply the division lemma to 614 and 6, to get
614 = 6 x 102 + 2
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 2 and 6, 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 6 and 614 is 2
Notice that 2 = HCF(6,2) = HCF(614,6) .
