Given numbers are 820, 434, 779, 528
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 434) = 177940
GCD(820, 434) = ( 820 x 434 ) / 177940
= 820 / 434
= 820
Step2:
LCM(2, 779) = 1558
GCD(2, 779) = ( 2 x 779 ) / 1558
= 2 / 779
= 2
Step3:
LCM(1, 528) = 528
GCD(1, 528) = ( 1 x 528 ) / 528
= 1 / 528
= 1
So, Greatest Common Divisor of 820, 434, 779, 528 is 1
