HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 949, 120 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 949, 120 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, 120 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, 120 is 1.
HCF(949, 120) = 1
HCF of 949, 120 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 949, 120 is 1.
Highest Common Factor of 949,120 is 1
Step 1: Since 949 > 120, we apply the division lemma to 949 and 120, to get
949 = 120 x 7 + 109
Step 2: Since the reminder 120 ≠ 0, we apply division lemma to 109 and 120, to get
120 = 109 x 1 + 11
Step 3: We consider the new divisor 109 and the new remainder 11, and apply the division lemma to get
109 = 11 x 9 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 949 and 120 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(109,11) = HCF(120,109) = HCF(949,120) .
