Given numbers are 278, 820, 899, 124

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

Apply this formula for all numbers.

Step1:

LCM(278, 820) = 113980

GCD(278, 820) = ( 278 x 820 ) / 113980

= 278 / 820

= 278

Step2:

LCM(2, 899) = 1798

GCD(2, 899) = ( 2 x 899 ) / 1798

= 2 / 899

= 2

Step3:

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

= 1 / 124

= 1

So, Greatest Common Divisor of 278, 820, 899, 124 is 1
