Given numbers are 780, 316, 181, 858
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 316) = 61620
GCD(780, 316) = ( 780 x 316 ) / 61620
= 780 / 316
= 780
Step2:
LCM(4, 181) = 724
GCD(4, 181) = ( 4 x 181 ) / 724
= 4 / 181
= 4
Step3:
LCM(1, 858) = 858
GCD(1, 858) = ( 1 x 858 ) / 858
= 1 / 858
= 1
So, Greatest Common Divisor of 780, 316, 181, 858 is 1
