Given numbers are 970, 707, 145, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(970, 707) = 685790
GCD(970, 707) = ( 970 x 707 ) / 685790
= 970 / 707
= 970
Step2:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 970, 707, 145, 639 is 1
