HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 949, 421, 721, 750 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 949, 421, 721, 750 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 949, 421, 721, 750 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 949, 421, 721, 750 is 1.
HCF(949, 421, 721, 750) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 949, 421, 721, 750 is 1.
Step 1: Since 949 > 421, we apply the division lemma to 949 and 421, to get
949 = 421 x 2 + 107
Step 2: Since the reminder 421 ≠ 0, we apply division lemma to 107 and 421, to get
421 = 107 x 3 + 100
Step 3: We consider the new divisor 107 and the new remainder 100, and apply the division lemma to get
107 = 100 x 1 + 7
We consider the new divisor 100 and the new remainder 7,and apply the division lemma to get
100 = 7 x 14 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 949 and 421 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(100,7) = HCF(107,100) = HCF(421,107) = HCF(949,421) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 721 > 1, we apply the division lemma to 721 and 1, to get
721 = 1 x 721 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 721 is 1
Notice that 1 = HCF(721,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 750 > 1, we apply the division lemma to 750 and 1, to get
750 = 1 x 750 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 750 is 1
Notice that 1 = HCF(750,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
