HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 650, 993, 720 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 650, 993, 720 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 650, 993, 720 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 650, 993, 720 is 1.
HCF(650, 993, 720) = 1
HCF of 650, 993, 720 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 650, 993, 720 is 1.
Highest Common Factor of 650,993,720 is 1
Step 1: Since 993 > 650, we apply the division lemma to 993 and 650, to get
993 = 650 x 1 + 343
Step 2: Since the reminder 650 ≠ 0, we apply division lemma to 343 and 650, to get
650 = 343 x 1 + 307
Step 3: We consider the new divisor 343 and the new remainder 307, and apply the division lemma to get
343 = 307 x 1 + 36
We consider the new divisor 307 and the new remainder 36,and apply the division lemma to get
307 = 36 x 8 + 19
We consider the new divisor 36 and the new remainder 19,and apply the division lemma to get
36 = 19 x 1 + 17
We consider the new divisor 19 and the new remainder 17,and apply the division lemma to get
19 = 17 x 1 + 2
We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get
17 = 2 x 8 + 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 650 and 993 is 1
Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(19,17) = HCF(36,19) = HCF(307,36) = HCF(343,307) = HCF(650,343) = HCF(993,650) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 720 > 1, we apply the division lemma to 720 and 1, to get
720 = 1 x 720 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 720 is 1
Notice that 1 = HCF(720,1) .
