HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 124, 577, 949 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 124, 577, 949 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 124, 577, 949 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 124, 577, 949 is 1.
HCF(124, 577, 949) = 1
HCF of 124, 577, 949 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 124, 577, 949 is 1.
Highest Common Factor of 124,577,949 is 1
Step 1: Since 577 > 124, we apply the division lemma to 577 and 124, to get
577 = 124 x 4 + 81
Step 2: Since the reminder 124 ≠ 0, we apply division lemma to 81 and 124, to get
124 = 81 x 1 + 43
Step 3: We consider the new divisor 81 and the new remainder 43, and apply the division lemma to get
81 = 43 x 1 + 38
We consider the new divisor 43 and the new remainder 38,and apply the division lemma to get
43 = 38 x 1 + 5
We consider the new divisor 38 and the new remainder 5,and apply the division lemma to get
38 = 5 x 7 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 124 and 577 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(38,5) = HCF(43,38) = HCF(81,43) = HCF(124,81) = HCF(577,124) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 949 > 1, we apply the division lemma to 949 and 1, to get
949 = 1 x 949 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 949 is 1
Notice that 1 = HCF(949,1) .
