Given numbers are 145, 970, 803, 663

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(145, 970) = 28130

GCD(145, 970) = ( 145 x 970 ) / 28130

= 145 / 970

= 145

Step2:

LCM(5, 803) = 4015

GCD(5, 803) = ( 5 x 803 ) / 4015

= 5 / 803

= 5

Step3:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

So, Greatest Common Divisor of 145, 970, 803, 663 is 1
