Given numbers are 157, 251, 705, 603
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(157, 251) = 39407
GCD(157, 251) = ( 157 x 251 ) / 39407
= 157 / 251
= 157
Step2:
LCM(1, 705) = 705
GCD(1, 705) = ( 1 x 705 ) / 705
= 1 / 705
= 1
Step3:
LCM(1, 603) = 603
GCD(1, 603) = ( 1 x 603 ) / 603
= 1 / 603
= 1
So, Greatest Common Divisor of 157, 251, 705, 603 is 1
