HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 565, 155, 738 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 565, 155, 738 is 1 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 565, 155, 738 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 565, 155, 738 is 1.
HCF(565, 155, 738) = 1
HCF of 565, 155, 738 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 565, 155, 738 is 1.
Highest Common Factor of 565,155,738 is 1
Step 1: Since 565 > 155, we apply the division lemma to 565 and 155, to get
565 = 155 x 3 + 100
Step 2: Since the reminder 155 ≠ 0, we apply division lemma to 100 and 155, to get
155 = 100 x 1 + 55
Step 3: We consider the new divisor 100 and the new remainder 55, and apply the division lemma to get
100 = 55 x 1 + 45
We consider the new divisor 55 and the new remainder 45,and apply the division lemma to get
55 = 45 x 1 + 10
We consider the new divisor 45 and the new remainder 10,and apply the division lemma to get
45 = 10 x 4 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 565 and 155 is 5
Notice that 5 = HCF(10,5) = HCF(45,10) = HCF(55,45) = HCF(100,55) = HCF(155,100) = HCF(565,155) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 738 > 5, we apply the division lemma to 738 and 5, to get
738 = 5 x 147 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 738 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(738,5) .
