GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 220) = 17820
GCD(810, 220) = ( 810 x 220 ) / 17820
= 810 / 220
= 810
Step2:
LCM(10, 766) = 3830
GCD(10, 766) = ( 10 x 766 ) / 3830
= 10 / 766
= 10
Step3:
LCM(2, 782) = 782
GCD(2, 782) = ( 2 x 782 ) / 782
= 2 / 782
= 2
So, Greatest Common Divisor of 810, 220, 766, 782 is 2
