HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 949, 680, 145, 111 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 949, 680, 145, 111 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, 680, 145, 111 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, 680, 145, 111 is 1.
HCF(949, 680, 145, 111) = 1
HCF of 949, 680, 145, 111 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, 680, 145, 111 is 1.
Highest Common Factor of 949,680,145,111 is 1
Step 1: Since 949 > 680, we apply the division lemma to 949 and 680, to get
949 = 680 x 1 + 269
Step 2: Since the reminder 680 ≠ 0, we apply division lemma to 269 and 680, to get
680 = 269 x 2 + 142
Step 3: We consider the new divisor 269 and the new remainder 142, and apply the division lemma to get
269 = 142 x 1 + 127
We consider the new divisor 142 and the new remainder 127,and apply the division lemma to get
142 = 127 x 1 + 15
We consider the new divisor 127 and the new remainder 15,and apply the division lemma to get
127 = 15 x 8 + 7
We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get
15 = 7 x 2 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 949 and 680 is 1
Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(127,15) = HCF(142,127) = HCF(269,142) = HCF(680,269) = HCF(949,680) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 145 > 1, we apply the division lemma to 145 and 1, to get
145 = 1 x 145 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 145 is 1
Notice that 1 = HCF(145,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 111 > 1, we apply the division lemma to 111 and 1, to get
111 = 1 x 111 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 111 is 1
Notice that 1 = HCF(111,1) .
