Given numbers are 557, 782, 158, 215

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

Apply this formula for all numbers.

Step1:

LCM(557, 782) = 435574

GCD(557, 782) = ( 557 x 782 ) / 435574

= 557 / 782

= 557

Step2:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1

Step3:

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

= 1 / 215

= 1

So, Greatest Common Divisor of 557, 782, 158, 215 is 1
