Given numbers are 620, 615, 818, 382
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 615) = 76260
GCD(620, 615) = ( 620 x 615 ) / 76260
= 620 / 615
= 620
Step2:
LCM(5, 818) = 4090
GCD(5, 818) = ( 5 x 818 ) / 4090
= 5 / 818
= 5
Step3:
LCM(1, 382) = 382
GCD(1, 382) = ( 1 x 382 ) / 382
= 1 / 382
= 1
So, Greatest Common Divisor of 620, 615, 818, 382 is 1
