Given numbers are 858, 521, 802, 790
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 521) = 447018
GCD(858, 521) = ( 858 x 521 ) / 447018
= 858 / 521
= 858
Step2:
LCM(1, 802) = 802
GCD(1, 802) = ( 1 x 802 ) / 802
= 1 / 802
= 1
Step3:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
So, Greatest Common Divisor of 858, 521, 802, 790 is 1
