Given numbers are 878, 661, 978, 370

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

Apply this formula for all numbers.

Step1:

LCM(878, 661) = 580358

GCD(878, 661) = ( 878 x 661 ) / 580358

= 878 / 661

= 878

Step2:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

Step3:

LCM(1, 370) = 370

GCD(1, 370) = ( 1 x 370 ) / 370

= 1 / 370

= 1

So, Greatest Common Divisor of 878, 661, 978, 370 is 1
