Given numbers are 978, 862, 619, 911
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 862) = 421518
GCD(978, 862) = ( 978 x 862 ) / 421518
= 978 / 862
= 978
Step2:
LCM(2, 619) = 1238
GCD(2, 619) = ( 2 x 619 ) / 1238
= 2 / 619
= 2
Step3:
LCM(1, 911) = 911
GCD(1, 911) = ( 1 x 911 ) / 911
= 1 / 911
= 1
So, Greatest Common Divisor of 978, 862, 619, 911 is 1
