Steps to Calculate GCD of 978, 313, 682, 648 using LCM Formula

Given numbers are 978, 313, 682, 648

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

Apply this formula for all numbers.

Step1:

LCM(978, 313) = 306114

GCD(978, 313) = ( 978 x 313 ) / 306114

= 978 / 313

= 978


Step2:

LCM(1, 682) = 682

GCD(1, 682) = ( 1 x 682 ) / 682

= 1 / 682

= 1


Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1


So, Greatest Common Divisor of 978, 313, 682, 648 is 1
