Given numbers are 658, 245, 278, 470

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

Apply this formula for all numbers.

Step1:

LCM(658, 245) = 23030

GCD(658, 245) = ( 658 x 245 ) / 23030

= 658 / 245

= 658

Step2:

LCM(7, 278) = 1946

GCD(7, 278) = ( 7 x 278 ) / 1946

= 7 / 278

= 7

Step3:

LCM(1, 470) = 470

GCD(1, 470) = ( 1 x 470 ) / 470

= 1 / 470

= 1

So, Greatest Common Divisor of 658, 245, 278, 470 is 1
