Given numbers are 920, 668, 511, 392
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(920, 668) = 153640
GCD(920, 668) = ( 920 x 668 ) / 153640
= 920 / 668
= 920
Step2:
LCM(4, 511) = 2044
GCD(4, 511) = ( 4 x 511 ) / 2044
= 4 / 511
= 4
Step3:
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
= 1 / 392
= 1
So, Greatest Common Divisor of 920, 668, 511, 392 is 1
