Given numbers are 715, 805, 831, 820
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(715, 805) = 115115
GCD(715, 805) = ( 715 x 805 ) / 115115
= 715 / 805
= 715
Step2:
LCM(5, 831) = 4155
GCD(5, 831) = ( 5 x 831 ) / 4155
= 5 / 831
= 5
Step3:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
So, Greatest Common Divisor of 715, 805, 831, 820 is 1
