HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 568, 620, 690 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 568, 620, 690 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 568, 620, 690 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 568, 620, 690 is 2.
HCF(568, 620, 690) = 2
HCF of 568, 620, 690 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 568, 620, 690 is 2.
Highest Common Factor of 568,620,690 is 2
Step 1: Since 620 > 568, we apply the division lemma to 620 and 568, to get
620 = 568 x 1 + 52
Step 2: Since the reminder 568 ≠ 0, we apply division lemma to 52 and 568, to get
568 = 52 x 10 + 48
Step 3: We consider the new divisor 52 and the new remainder 48, and apply the division lemma to get
52 = 48 x 1 + 4
We consider the new divisor 48 and the new remainder 4, and apply the division lemma to get
48 = 4 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 568 and 620 is 4
Notice that 4 = HCF(48,4) = HCF(52,48) = HCF(568,52) = HCF(620,568) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 690 > 4, we apply the division lemma to 690 and 4, to get
690 = 4 x 172 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, 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 4 and 690 is 2
Notice that 2 = HCF(4,2) = HCF(690,4) .
