HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 649, 365, 533 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 649, 365, 533 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 649, 365, 533 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 649, 365, 533 is 1.
HCF(649, 365, 533) = 1
HCF of 649, 365, 533 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 649, 365, 533 is 1.
Highest Common Factor of 649,365,533 is 1
Step 1: Since 649 > 365, we apply the division lemma to 649 and 365, to get
649 = 365 x 1 + 284
Step 2: Since the reminder 365 ≠ 0, we apply division lemma to 284 and 365, to get
365 = 284 x 1 + 81
Step 3: We consider the new divisor 284 and the new remainder 81, and apply the division lemma to get
284 = 81 x 3 + 41
We consider the new divisor 81 and the new remainder 41,and apply the division lemma to get
81 = 41 x 1 + 40
We consider the new divisor 41 and the new remainder 40,and apply the division lemma to get
41 = 40 x 1 + 1
We consider the new divisor 40 and the new remainder 1,and apply the division lemma to get
40 = 1 x 40 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 649 and 365 is 1
Notice that 1 = HCF(40,1) = HCF(41,40) = HCF(81,41) = HCF(284,81) = HCF(365,284) = HCF(649,365) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 533 > 1, we apply the division lemma to 533 and 1, to get
533 = 1 x 533 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 533 is 1
Notice that 1 = HCF(533,1) .
