Given numbers are 665, 308, 253, 157
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 308) = 29260
GCD(665, 308) = ( 665 x 308 ) / 29260
= 665 / 308
= 665
Step2:
LCM(7, 253) = 1771
GCD(7, 253) = ( 7 x 253 ) / 1771
= 7 / 253
= 7
Step3:
LCM(1, 157) = 157
GCD(1, 157) = ( 1 x 157 ) / 157
= 1 / 157
= 1
So, Greatest Common Divisor of 665, 308, 253, 157 is 1
