HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 428, 740, 119 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 428, 740, 119 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 428, 740, 119 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 428, 740, 119 is 1.
HCF(428, 740, 119) = 1
HCF of 428, 740, 119 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 428, 740, 119 is 1.
Highest Common Factor of 428,740,119 is 1
Step 1: Since 740 > 428, we apply the division lemma to 740 and 428, to get
740 = 428 x 1 + 312
Step 2: Since the reminder 428 ≠ 0, we apply division lemma to 312 and 428, to get
428 = 312 x 1 + 116
Step 3: We consider the new divisor 312 and the new remainder 116, and apply the division lemma to get
312 = 116 x 2 + 80
We consider the new divisor 116 and the new remainder 80,and apply the division lemma to get
116 = 80 x 1 + 36
We consider the new divisor 80 and the new remainder 36,and apply the division lemma to get
80 = 36 x 2 + 8
We consider the new divisor 36 and the new remainder 8,and apply the division lemma to get
36 = 8 x 4 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 428 and 740 is 4
Notice that 4 = HCF(8,4) = HCF(36,8) = HCF(80,36) = HCF(116,80) = HCF(312,116) = HCF(428,312) = HCF(740,428) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 119 > 4, we apply the division lemma to 119 and 4, to get
119 = 4 x 29 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 119 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(119,4) .
