Given numbers are 215, 820, 719, 557

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

Apply this formula for all numbers.

Step1:

LCM(215, 820) = 35260

GCD(215, 820) = ( 215 x 820 ) / 35260

= 215 / 820

= 215

Step2:

LCM(5, 719) = 3595

GCD(5, 719) = ( 5 x 719 ) / 3595

= 5 / 719

= 5

Step3:

LCM(1, 557) = 557

GCD(1, 557) = ( 1 x 557 ) / 557

= 1 / 557

= 1

So, Greatest Common Divisor of 215, 820, 719, 557 is 1
