Given numbers are 245, 215, 670, 370

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

Apply this formula for all numbers.

Step1:

LCM(245, 215) = 10535

GCD(245, 215) = ( 245 x 215 ) / 10535

= 245 / 215

= 245

Step2:

LCM(5, 670) = 670

GCD(5, 670) = ( 5 x 670 ) / 670

= 5 / 670

= 5

Step3:

LCM(5, 370) = 370

GCD(5, 370) = ( 5 x 370 ) / 370

= 5 / 370

= 5

So, Greatest Common Divisor of 245, 215, 670, 370 is 5
