HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 620, 757, 954 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 620, 757, 954 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 620, 757, 954 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 620, 757, 954 is 1.
HCF(620, 757, 954) = 1
HCF of 620, 757, 954 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 620, 757, 954 is 1.
Highest Common Factor of 620,757,954 is 1
Step 1: Since 757 > 620, we apply the division lemma to 757 and 620, to get
757 = 620 x 1 + 137
Step 2: Since the reminder 620 ≠ 0, we apply division lemma to 137 and 620, to get
620 = 137 x 4 + 72
Step 3: We consider the new divisor 137 and the new remainder 72, and apply the division lemma to get
137 = 72 x 1 + 65
We consider the new divisor 72 and the new remainder 65,and apply the division lemma to get
72 = 65 x 1 + 7
We consider the new divisor 65 and the new remainder 7,and apply the division lemma to get
65 = 7 x 9 + 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 620 and 757 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(65,7) = HCF(72,65) = HCF(137,72) = HCF(620,137) = HCF(757,620) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 954 > 1, we apply the division lemma to 954 and 1, to get
954 = 1 x 954 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 954 is 1
Notice that 1 = HCF(954,1) .
