Given numbers are 870, 573, 258, 647
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 573) = 166170
GCD(870, 573) = ( 870 x 573 ) / 166170
= 870 / 573
= 870
Step2:
LCM(3, 258) = 258
GCD(3, 258) = ( 3 x 258 ) / 258
= 3 / 258
= 3
Step3:
LCM(3, 647) = 1941
GCD(3, 647) = ( 3 x 647 ) / 1941
= 3 / 647
= 3
So, Greatest Common Divisor of 870, 573, 258, 647 is 1
