Given numbers are 528, 365, 420, 813
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(528, 365) = 192720
GCD(528, 365) = ( 528 x 365 ) / 192720
= 528 / 365
= 528
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
= 1 / 813
= 1
So, Greatest Common Divisor of 528, 365, 420, 813 is 1
