Steps to Calculate GCD of 978, 272, 434, 755 using LCM Formula

Given numbers are 978, 272, 434, 755

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

Apply this formula for all numbers.

Step1:

LCM(978, 272) = 133008

GCD(978, 272) = ( 978 x 272 ) / 133008

= 978 / 272

= 978


Step2:

LCM(2, 434) = 434

GCD(2, 434) = ( 2 x 434 ) / 434

= 2 / 434

= 2


Step3:

LCM(2, 755) = 1510

GCD(2, 755) = ( 2 x 755 ) / 1510

= 2 / 755

= 2


So, Greatest Common Divisor of 978, 272, 434, 755 is 1
