HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 690, 153, 312, 580 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 690, 153, 312, 580 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 690, 153, 312, 580 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 690, 153, 312, 580 is 1.
HCF(690, 153, 312, 580) = 1
HCF of 690, 153, 312, 580 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 690, 153, 312, 580 is 1.
Highest Common Factor of 690,153,312,580 is 1
Step 1: Since 690 > 153, we apply the division lemma to 690 and 153, to get
690 = 153 x 4 + 78
Step 2: Since the reminder 153 ≠ 0, we apply division lemma to 78 and 153, to get
153 = 78 x 1 + 75
Step 3: We consider the new divisor 78 and the new remainder 75, and apply the division lemma to get
78 = 75 x 1 + 3
We consider the new divisor 75 and the new remainder 3, and apply the division lemma to get
75 = 3 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 690 and 153 is 3
Notice that 3 = HCF(75,3) = HCF(78,75) = HCF(153,78) = HCF(690,153) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 312 > 3, we apply the division lemma to 312 and 3, to get
312 = 3 x 104 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 312 is 3
Notice that 3 = HCF(312,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 580 > 3, we apply the division lemma to 580 and 3, to get
580 = 3 x 193 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 580 is 1
Notice that 1 = HCF(3,1) = HCF(580,3) .
