Given numbers are 245, 557, 946, 666

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

Apply this formula for all numbers.

Step1:

LCM(245, 557) = 136465

GCD(245, 557) = ( 245 x 557 ) / 136465

= 245 / 557

= 245

Step2:

LCM(1, 946) = 946

GCD(1, 946) = ( 1 x 946 ) / 946

= 1 / 946

= 1

Step3:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1

So, Greatest Common Divisor of 245, 557, 946, 666 is 1
