Given numbers are 855, 974, 761, 578
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 974) = 832770
GCD(855, 974) = ( 855 x 974 ) / 832770
= 855 / 974
= 855
Step2:
LCM(1, 761) = 761
GCD(1, 761) = ( 1 x 761 ) / 761
= 1 / 761
= 1
Step3:
LCM(1, 578) = 578
GCD(1, 578) = ( 1 x 578 ) / 578
= 1 / 578
= 1
So, Greatest Common Divisor of 855, 974, 761, 578 is 1
