Steps to Calculate GCD of 665, 615, 292, 343 using LCM Formula

Given numbers are 665, 615, 292, 343

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(665, 615) = 81795

GCD(665, 615) = ( 665 x 615 ) / 81795

= 665 / 615

= 665


Step2:

LCM(5, 292) = 1460

GCD(5, 292) = ( 5 x 292 ) / 1460

= 5 / 292

= 5


Step3:

LCM(1, 343) = 343

GCD(1, 343) = ( 1 x 343 ) / 343

= 1 / 343

= 1


So, Greatest Common Divisor of 665, 615, 292, 343 is 1
