Given numbers are 768, 609, 392, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(768, 609) = 155904
GCD(768, 609) = ( 768 x 609 ) / 155904
= 768 / 609
= 768
Step2:
LCM(3, 392) = 1176
GCD(3, 392) = ( 3 x 392 ) / 1176
= 3 / 392
= 3
Step3:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
So, Greatest Common Divisor of 768, 609, 392, 445 is 1
