Given numbers are 830, 945, 868, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(830, 945) = 156870
GCD(830, 945) = ( 830 x 945 ) / 156870
= 830 / 945
= 830
Step2:
LCM(5, 868) = 4340
GCD(5, 868) = ( 5 x 868 ) / 4340
= 5 / 868
= 5
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 830, 945, 868, 620 is 1
