Given numbers are 665, 615, 292, 343
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 615) = 81795
GCD(665, 615) = ( 665 x 615 ) / 81795
= 665 / 615
= 665
Step2:
LCM(5, 292) = 1460
GCD(5, 292) = ( 5 x 292 ) / 1460
= 5 / 292
= 5
Step3:
LCM(1, 343) = 343
GCD(1, 343) = ( 1 x 343 ) / 343
= 1 / 343
= 1
So, Greatest Common Divisor of 665, 615, 292, 343 is 1
