HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 649, 531, 741 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 649, 531, 741 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, 531, 741 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, 531, 741 is 1.
HCF(649, 531, 741) = 1
HCF of 649, 531, 741 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, 531, 741 is 1.
Highest Common Factor of 649,531,741 is 1
Step 1: Since 649 > 531, we apply the division lemma to 649 and 531, to get
649 = 531 x 1 + 118
Step 2: Since the reminder 531 ≠ 0, we apply division lemma to 118 and 531, to get
531 = 118 x 4 + 59
Step 3: We consider the new divisor 118 and the new remainder 59, and apply the division lemma to get
118 = 59 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 59, the HCF of 649 and 531 is 59
Notice that 59 = HCF(118,59) = HCF(531,118) = HCF(649,531) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 741 > 59, we apply the division lemma to 741 and 59, to get
741 = 59 x 12 + 33
Step 2: Since the reminder 59 ≠ 0, we apply division lemma to 33 and 59, to get
59 = 33 x 1 + 26
Step 3: We consider the new divisor 33 and the new remainder 26, and apply the division lemma to get
33 = 26 x 1 + 7
We consider the new divisor 26 and the new remainder 7,and apply the division lemma to get
26 = 7 x 3 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 59 and 741 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(26,7) = HCF(33,26) = HCF(59,33) = HCF(741,59) .
