HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 785, 278, 79, 154 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 785, 278, 79, 154 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 785, 278, 79, 154 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 785, 278, 79, 154 is 1.
HCF(785, 278, 79, 154) = 1
HCF of 785, 278, 79, 154 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 785, 278, 79, 154 is 1.
Highest Common Factor of 785,278,79,154 is 1
Step 1: Since 785 > 278, we apply the division lemma to 785 and 278, to get
785 = 278 x 2 + 229
Step 2: Since the reminder 278 ≠ 0, we apply division lemma to 229 and 278, to get
278 = 229 x 1 + 49
Step 3: We consider the new divisor 229 and the new remainder 49, and apply the division lemma to get
229 = 49 x 4 + 33
We consider the new divisor 49 and the new remainder 33,and apply the division lemma to get
49 = 33 x 1 + 16
We consider the new divisor 33 and the new remainder 16,and apply the division lemma to get
33 = 16 x 2 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 785 and 278 is 1
Notice that 1 = HCF(16,1) = HCF(33,16) = HCF(49,33) = HCF(229,49) = HCF(278,229) = HCF(785,278) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 79 > 1, we apply the division lemma to 79 and 1, to get
79 = 1 x 79 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 79 is 1
Notice that 1 = HCF(79,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 154 > 1, we apply the division lemma to 154 and 1, to get
154 = 1 x 154 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 154 is 1
Notice that 1 = HCF(154,1) .
