Given numbers are 839, 775, 630, 715
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(839, 775) = 650225
GCD(839, 775) = ( 839 x 775 ) / 650225
= 839 / 775
= 839
Step2:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
Step3:
LCM(1, 715) = 715
GCD(1, 715) = ( 1 x 715 ) / 715
= 1 / 715
= 1
So, Greatest Common Divisor of 839, 775, 630, 715 is 1
