HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 610, 785, 553, 70 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 610, 785, 553, 70 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 610, 785, 553, 70 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 610, 785, 553, 70 is 1.
HCF(610, 785, 553, 70) = 1
HCF of 610, 785, 553, 70 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 610, 785, 553, 70 is 1.
Highest Common Factor of 610,785,553,70 is 1
Step 1: Since 785 > 610, we apply the division lemma to 785 and 610, to get
785 = 610 x 1 + 175
Step 2: Since the reminder 610 ≠ 0, we apply division lemma to 175 and 610, to get
610 = 175 x 3 + 85
Step 3: We consider the new divisor 175 and the new remainder 85, and apply the division lemma to get
175 = 85 x 2 + 5
We consider the new divisor 85 and the new remainder 5, and apply the division lemma to get
85 = 5 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 610 and 785 is 5
Notice that 5 = HCF(85,5) = HCF(175,85) = HCF(610,175) = HCF(785,610) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 553 > 5, we apply the division lemma to 553 and 5, to get
553 = 5 x 110 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: 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 5 and 553 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(553,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 70 > 1, we apply the division lemma to 70 and 1, to get
70 = 1 x 70 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 70 is 1
Notice that 1 = HCF(70,1) .
