Given numbers are 801, 780, 840, 549
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(801, 780) = 208260
GCD(801, 780) = ( 801 x 780 ) / 208260
= 801 / 780
= 801
Step2:
LCM(3, 840) = 840
GCD(3, 840) = ( 3 x 840 ) / 840
= 3 / 840
= 3
Step3:
LCM(3, 549) = 549
GCD(3, 549) = ( 3 x 549 ) / 549
= 3 / 549
= 3
So, Greatest Common Divisor of 801, 780, 840, 549 is 3
