Given numbers are 158, 530, 700, 785
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(158, 530) = 41870
GCD(158, 530) = ( 158 x 530 ) / 41870
= 158 / 530
= 158
Step2:
LCM(2, 700) = 700
GCD(2, 700) = ( 2 x 700 ) / 700
= 2 / 700
= 2
Step3:
LCM(2, 785) = 1570
GCD(2, 785) = ( 2 x 785 ) / 1570
= 2 / 785
= 2
So, Greatest Common Divisor of 158, 530, 700, 785 is 1
