Given numbers are 357, 245, 913, 215

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

Apply this formula for all numbers.

Step1:

LCM(357, 245) = 12495

GCD(357, 245) = ( 357 x 245 ) / 12495

= 357 / 245

= 357

Step2:

LCM(7, 913) = 6391

GCD(7, 913) = ( 7 x 913 ) / 6391

= 7 / 913

= 7

Step3:

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

= 1 / 215

= 1

So, Greatest Common Divisor of 357, 245, 913, 215 is 1
