HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 388, 645, 650 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 388, 645, 650 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 388, 645, 650 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 388, 645, 650 is 1.
HCF(388, 645, 650) = 1
HCF of 388, 645, 650 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 388, 645, 650 is 1.
Highest Common Factor of 388,645,650 is 1
Step 1: Since 645 > 388, we apply the division lemma to 645 and 388, to get
645 = 388 x 1 + 257
Step 2: Since the reminder 388 ≠ 0, we apply division lemma to 257 and 388, to get
388 = 257 x 1 + 131
Step 3: We consider the new divisor 257 and the new remainder 131, and apply the division lemma to get
257 = 131 x 1 + 126
We consider the new divisor 131 and the new remainder 126,and apply the division lemma to get
131 = 126 x 1 + 5
We consider the new divisor 126 and the new remainder 5,and apply the division lemma to get
126 = 5 x 25 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 388 and 645 is 1
Notice that 1 = HCF(5,1) = HCF(126,5) = HCF(131,126) = HCF(257,131) = HCF(388,257) = HCF(645,388) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 650 > 1, we apply the division lemma to 650 and 1, to get
650 = 1 x 650 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 650 is 1
Notice that 1 = HCF(650,1) .
