Steps to Calculate GCD of 258, 785, 131, 987 using LCM Formula

Given numbers are 258, 785, 131, 987

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

Apply this formula for all numbers.

Step1:

LCM(258, 785) = 202530

GCD(258, 785) = ( 258 x 785 ) / 202530

= 258 / 785

= 258


Step2:

LCM(1, 131) = 131

GCD(1, 131) = ( 1 x 131 ) / 131

= 1 / 131

= 1


Step3:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1


So, Greatest Common Divisor of 258, 785, 131, 987 is 1
